Do not operate beyond 125 °C for extended periods of time. Operation above 150 °C may cause permanent damage to the IC. See Table 5 for thermal protection features. 7. Pin soldering temperature limit is for 10 seconds maximum duration. Not designed for immersion soldering. Exceeding these limits may cause a malfunction or permanent damage to the device. 8. Freescale’s Package Reflow capability meets Pb-free requirements for JEDEC standard J-STD-020C. For Peak Package Reflow Temperature and Moisture Sensitivity Levels (MSL), Go to www.freescale.com, search by part number [e.g. remove prefixes/suffixes and enter the core ID to view all orderable parts (i.e. MC33xxxD enter 33xxx), and review parametrics. 9. Junction temperature is a function of die size, on-chip power dissipation, package thermal resistance, mounting site (board) temperature, ambient temperature, air flow, power dissipation of other components on the board, and board thermal resistance. 10. The Board uses the JEDEC specifications for thermal testing (and simulation) JESD51-7 and JESD51-5. 11. Per JEDEC JESD51-6 with the board horizontal. 12. Thermal resistance between the die and the printed circuit board per JEDEC JESD51-8. Board temperature is measured on the top surface of the board near the package. 13. Thermal resistance between the die and the case top surface as measured by the cold plate method (MIL SPEC-883 Method 1012.1). 14. Thermal characterization parameter indicating the temperature difference between package top and the junction temperature per JEDEC JESD512. When Greek letters are not available, the thermal characterization parameter is written as Psi-JT. 4.2.1 Power Dissipation During operation, the temperature of the die should not exceed the operating junction temperature noted in Table 4. To optimize the thermal management and to avoid overheating, the PF0200 provides thermal protection. An internal comparator monitors the die temperature. Interrupts THERM110I, THERM120I, THERM125I, and THERM130I will be generated when the respective thresholds specified in Table 5 are crossed in either direction. The temperature range can be determined by reading the THERMxxxS bits in register INTSENSE0. In the event of excessive power dissipation, thermal protection circuitry will shut down the PF0200. This thermal protection will act above the thermal protection threshold listed in Table 5. To avoid any unwanted power downs resulting from internal noise, the protection is debounced for 8.0 ms. This protection should be considered as a fail-safe mechanism and therefore the system should be configured such that this protection is not tripped under normal conditions.

Functional Block Diagram 5.3 Functional Description 5.3.1 Power Generation The PF0200 PMIC features three buck regulators (up to four independent outputs), one boost regulator, six general purpose LDOs, one switch/LDO combination and a DDR voltage reference to supply voltages for the application processor and peripheral devices. The number of independent buck regulator outputs can be configured from three to four, thereby providing flexibility to operate with higher current capability, or to operate as independent outputs for applications requiring more voltage rails with lower current demands. The SW3 regulator can be configured as a single phase or with two independent outputs. The buck regulators provide the supply to processor cores and to other low-voltage circuits such as IO and memory. Dynamic voltage scaling is provided to allow controlled supply rail adjustments for the processor cores and/or other circuitry. Depending on the system power path configuration, the six general purpose LDO regulators can be directly supplied from the main input supply or from the switching regulators to power peripherals, such as audio, camera, Bluetooth, Wireless LAN, etc. A specific VREFDDR voltage reference is included to provide accurate reference voltage for DDR memories operating with or without VTT termination. The VSNVS block behaves as an LDO, or as a bypass switch to supply the SNVS/SRTC circuitry on the i.MX processors; VSNVS may be powered from VIN, or from a coin cell. 5.3.2 Control Logic The PF0200 PMIC is fully programmable via the I2C interface. Additional communication is provided by direct logic interfacing including interrupt and reset. Start-up sequence of the device is selected upon the initial OTP configuration explained in the Start-up section, or by configuring the “Try Before Buy” feature to test different power up sequences before choosing the final OTP configuration. The PF0200 PMIC has the interfaces for the power buttons and dedicated signaling interfacing with the processor. It also ensures supply of critical internal logic and other circuits from the coin cell in case of brief interruptions from the main battery. A charger for the coin cell is included as well. PF0200 Analog Integrated Circuit Device Data Freescale Semiconductor 15 GENERAL DESCRIPTION FUNCTIONAL DESCRIPTION 5.3.2.1 Interface Signals PWRON PWRON is an input signal to the IC that generates a turn-on event. It can be configured to detect a level, or an edge using the PWRON_CFG bit. Refer to section Turn On Events for more details. STANDBY STANDBY is an input signal to the IC. When it is asserted the part enters standby mode and when de-asserted, the part exits standby mode. STANDBY can be configured as active high or active low using the STANDBYINV bit. Refer to the section Standby Mode for more details. Note: When operating the PMIC at VIN 2.85 V and VSNVS is programmed for a 3.0 V output, a coin cell must be present to provide VSNVS, or the PMIC will not reliably enter and exit the STANDBY mode. RESETBMCU RESETBMCU is an open-drain, active low output configurable for two modes of operation. In its default mode, it is de-asserted 2.0 to 4.0 ms after the last regulator in the start-up sequence is enabled; refer to Figure 6 as an example. In this mode, the signal can be used to bring the processor out of reset, or as an indicator that all supplies have been enabled; it is only asserted for a turn-off event. When configured for its fault mode, RESETBMCU is de-asserted after the start-up sequence is completed only if no faults occurred during start-up. At anytime, if a fault occurs and persists for 1.8 ms typically, RESETBMCU is asserted, LOW. The PF0200 is turned off if the fault persists for more than 100 ms typically. The PWRON signal restarts the part, though if the fault persists, the sequence described above will be repeated. To enter the fault mode, set bit OTP_PG_EN of register OTP PWRGD EN to “1”. This register, 0xE8, is located on Extended Page 1 of the register map. To test the fault mode, the bit may be set during TBB prototyping, or the mode may be permanently chosen by programming OTP fuses. SDWNB SDWNB is an open-drain, active low output that notifies the processor of an imminent PMIC shutdown. It is asserted low for one 32 kHz clock cycle before powering down and is then de-asserted in the OFF state. INTB INTB is an open-drain, active low output. It is asserted when any fault occurs, provided that the fault interrupt is unmasked. INTB is deasserted after the fault interrupt is cleared by software, which requires writing a “1” to the fault interrupt bit. PF0200 16 Analog Integrated Circuit Device Data Freescale Semiconductor FUNCTIONAL BLOCK REQUIREMENTS AND BEHAVIORS START-UP 6 Functional Block Requirements and Behaviors 6.1 Start-up The PF0200 can be configured to start-up from either the internal OTP configuration, or with a hard-coded configuration built into the device. The internal hard-coded configuration is enabled by connecting the VDDOTP pin to VCOREDIG through a 100 kohm resistor. The OTP configuration is enabled by connecting VDDOTP to GND. For NP devices, selecting the OTP configuration causes the PF0200 to not start-up. However, the PF0200 can be controlled through the I2C port for prototyping and programming. Once programmed, the NP device will startup with the customer programmed configuration. 6.1.1 Device Start-up Configuration Table 8 shows the Default Configuration which can be accessed on all devices as described above, as well as the pre-programmed OTP configurations.

Rise time is a function of slew rate of regulators and nominal voltage selected. 6.1.2 One Time Programmability (OTP) OTP allows the programming of start-up configurations for a variety of applications. Before permanently programming the IC by programming fuses, a configuration may be prototyped by using the “Try Before Buy” (TBB) feature. An error correction code(ECC) algorithm is available to correct a single bit error and to detect multiple bit errors when fuses are programmed. The parameters that can be configured by OTP are listed below. • General: I2C slave address, PWRON pin configuration, start-up sequence and timing • Buck regulators: Output voltage, single phase or independent mode configuration, switching frequency, and soft start ramp rate • Boost regulator and LDOs: Output voltage NOTE: When prototyping or programming fuses, the user must ensure that register settings are consistent with the hardware configuration. This is most important for the buck regulators, where the quantity, size, and value of the inductors depend on the configuration (single phase or independent mode) and the switching frequency. Additionally, if an LDO is powered by a buck regulator, it will be gated by the buck regulator in the start-up sequence. 6.1.2.1 Start-up Sequence and Timing Each regulator has 5-bits allocated to program its start-up time slot from a turn on event; therefore, each can be placed from position one to thirty-one in the start-up sequence. The all zeros code indicates that a regulator is not part of the start-up sequence and will remain off. See Table 10. The delay between each position is equal; however, four delay options are available. See Table 11. The start-up sequence will terminate at the last programmed regulator.

As a level sensitive input, an active high signal turns on the part and an active low signal turns off the part, or puts it into Sleep mode. As an edge sensitive input, such as when connected to a mechanical switch, a falling edge will turn on the part and if the switch is held low for greater than or equal to 4.0 seconds, the part will turn off or enter Sleep mode.

This allows flexibility to change the I2C address to avoid bus conflicts. Address bit, I2C_SLV_ADDR[3] in OTP_I2C_ADDR register is hard coded to “1” while the lower three LSBs of the I2C address (I2C_SLV_ADDR[2:0]) are programmable as shown in Table 13. Table 13.

The configuration is loaded from the OTP registers with this feature. These registers merely serve as temporary storage for the values to be written to the fuses, for the values read from the fuses, or for the values read from the default configuration. To avoid confusion, these registers will be referred to as the TBBOTP registers. The portion of the register map that concerns OTP is shown in Table 121 and Table 122. The contents of the TBBOTP registers are initialized to zero when a valid VIN is first applied. The values that are then loaded into the TBBOTP registers depend on the setting of the VDDOTP pin and on the value of the TBB_POR and FUSE_POR_XOR bits. Refer to Table 14. • If VDDOTP = VCOREDIG (1.5 V), the values are loaded from the default configuration. • If VDDOTP = 0.0 V, TBB_POR = 0 and FUSE_POR_XOR = 1, the values are loaded from the fuses. It is required to set all the FUSE_PORx bits to load the fuses. • If VDDOTP = 0.0 V, TBB_POR = 0 and FUSE_POR_XOR = 0, the TBBOTP registers remain initialized at zero. The initial value of TBB_POR is always “0”; only when VDDOTP = 0.0 V and TBB_POR is set to “1” are the values from the TBBOTP registers maintained and not loaded from a different source. The contents of the TBBOTP registers are modified by I2C. To communicate with I2C, VIN must be valid and VDDIO, to which SDA and SCL are pulled up, must be powered by a 1.7 to 3.6 V supply. VIN, or the coin cell voltage must be valid to maintain the contents of the registers. To power on with the contents of the TBBOTP registers, the following conditions must exist; VIN is valid, VDDOTP = 0.0 V, TBB_POR = 1 and there is a valid turn-on event. 6.1.4 Reading OTP Fuses As described in the previous section, the contents of the fuses are loaded to the TBBOTP registers. When the following conditions are met; VIN is valid, VDDOTP = 0.0 V, TBB_POR = 0, and FUSE_POR_XOR = 1. If ECC is enabled at the time the fuses were programmed, the error corrected values can be loaded into the TBBOTP registers if desired. Once the fuses are loaded and a turn-on event occurs, the PMIC will power on with the configuration programmed in the fuses. Contact your Freescale representative for more details on reading the OTP fuses. 6.1.5 Programming OTP Fuses The parameters that can be programmed are shown in the TBBOTP registers in the Extended Page 1 of the register map. The PF0200 offers ECC, the control registers for which functions are located in Extended Page 2 of the register map. There are ten banks of twentysix fuses, each that can be programmed.

By changing the factory trim values of the 16MHz clock, the user may add an offset as small as 3.0% of the nominal frequency. 6.3 Bias and References Block Description 6.3.1 Internal Core Voltage References All regulators use the main bandgap as the reference. The main bandgap is bypassed with a capacitor at VCOREREF. The bandgap and the rest of the core circuitry are supplied from VCORE. The performance of the regulators is directly dependent on the performance of the bandgap. No external DC loading is allowed on VCORE, VCOREDIG, or VCOREREF. VCOREDIG is kept powered as long as there is a valid supply and/or valid coin cell. Table 16 shows the main characteristics of the core circuitry.

Figure 8 shows the state diagram of the PF0200, along with the conditions to enter and exit from each state.

State Diagram To complement the state diagram in Figure 8, a description of the states is provided in following sections. Note that VIN must exceed the rising UVDET threshold to allow a power up. Refer to Table 27 for the UVDET thresholds. Additionally, I2C control is not possible in the Coin Cell mode and the interrupt signal, INTB, is only active in Sleep, Standby, and ON states. 6.4.1.1 ON Mode The PF0200 enters the On mode after a turn-on event. RESETBMCU is de-asserted, high, in this mode of operation. 6.4.1.2 OFF Mode The PF0200 enters the Off mode after a turn-off event. A thermal shutdown event also forces the PF0200 into the Off mode. Only VCOREDIG and VSNVS are powered in the mode of operation. To exit the Off mode, a valid turn-on event is required. RESETBMCU is asserted, LOW, in this mode. 6.4.1.3 Standby Mode • Depending on STANDBY pin configuration, Standby is entered when the STANDBY pin is asserted. This is typically used for lowpower mode of operation. • When STANDBY is de-asserted, Standby mode is exited. PF0200 26 Analog Integrated Circuit Device Data Freescale Semiconductor FUNCTIONAL BLOCK REQUIREMENTS AND BEHAVIORS POWER GENERATION A product may be designed to go into a Low-power mode after periods of inactivity. The STANDBY pin is provided for board level control of going in and out of such deep sleep modes (DSM). When a product is in DSM, it may be able to reduce the overall platform current by lowering the regulator output voltage, changing the operating mode of the regulators or disabling some regulators. The configuration of the regulators in Standby is pre-programmed through the I2C interface. Note that the STANDBY pin is programmable for Active High or Active Low polarity, and that decoding of a Standby event will take into account the programmed input polarity as shown in Table 21. When the PF0200 is powered up first, regulator settings for the Standby mode are mirrored from the regulator settings for the ON mode. To change the STANDBY pin polarity to Active Low, set the STANDBYINV bit via software first, and then change the regulator settings for Standby mode as required. For simplicity, STANDBY will generally be referred to as active high throughout this document. Table 21. Standby Pin and Polarity Control STANDBY (Pin)(33) STANDBYINV (I2C bit)(34) STANDBY Control (32) 0 0 0 0 1 1 1 0 1 1 1 0 Notes 32. STANDBY = 0: System is not in Standby, STANDBY = 1: System is in Standby 33. The state of the STANDBY pin only has influence in On mode. 34. Bit 6 in Power Control Register (ADDR - 0x1B) Since STANDBY pin activity is driven asynchronously to the system, a finite time is required for the internal logic to qualify and respond to the pin level changes. A programmable delay is provided to hold off the system response to a Standby event. This allows the processor and peripherals some time after a standby instruction has been received to terminate processes to facilitate seamless entering into Standby mode. When enabled (STBYDLY = 01, 10, or 11) per Table 22, STBYDLY will delay the Standby initiated response for the entire IC, until the STBYDLY counter expires. An allowance should be made for three additional 32 k cycles required to synchronize the Standby event. Table 22. STANDBY Delay - Initiated Response STBYDLY[1:0](35) Function 00 No Delay 01 One 32 k period (default) 10 Two 32 k periods 11 Three 32 k periods Notes 35. Bits [5:4] in Power Control Register (ADDR - 0x1B) 6.4.1.4 Sleep Mode • Depending on PWRON pin configuration, Sleep mode is entered when PWRON is de-asserted and SWxOMODE bit is set. • To exit Sleep mode, assert the PWRON pin. In the Sleep mode, the regulator will use the set point as programmed by SW1ABOFF[5:0] for SW1A/B and by SWxOFF[6:0] for SW2 and SW3A/B. The activated regulators will maintain settings for this mode and voltage until the next turn-on event. Table 23 shows the control bits in Sleep mode. During Sleep mode, interrupts are active and the INTB pin will report any unmasked fault event. PF0200 Analog Integrated Circuit Device Data Freescale Semiconductor 27 FUNCTIONAL BLOCK REQUIREMENTS AND BEHAVIORS POWER GENERATION Table 23. Regulator Mode Control SWxOMODE Off Operational Mode (Sleep) (36) 0 Off 1 PFM Notes 36. For sleep mode, an activated switching regulator, should use the off mode set point as programmed by SW1ABOFF[5:0] for SW1A/B and SWxOFF[6:0] for SW2 and SW3A/B. 6.4.1.5 Coin Cell Mode In the Coin Cell state, the coin cell is the only valid power source (VIN = 0.0 V) to the PMIC. No turn-on event is accepted in the Coin Cell state. Transition to the OFF state requires that VIN surpasses UVDET threshold. RESETBMCU is held low in this mode. If the coin cell is depleted, a complete system reset will occur. At the next application of power and the detection of a Turn-on event, the system will be re-initialized with all I2C bits including those that reset on COINPORB, are restored to their default states. 6.4.2 State Machine Flow Summary Table 24 provides a summary matrix of the PF0200 flow diagram to show the conditions needed to transition from one state to another.

The type of Turn-on event depends on the configuration of PWRON. PWRON may be configured as an active high when PWRON_CFG = 0, or as the input of a mechanical switch when PWRON_CFG = 1. VIN must be greater than UVDET for the PMIC to turn-on. When PWRON is configured as an active high and PWRON is high (pulled up to VSNVS) before VIN is valid, a VIN transition from 0.0 V to a voltage greater than UVDET is also a Turn-on event. See the State diagram, Figure 8, and the Table 24 for more details. Any regulator enabled in the Sleep mode will remain enabled when transitioning from Sleep to ON, i.e., the regulator will not be turned off and then on again to match the start-up sequence. The following is a more detailed description of the PWRON configurations: • If PWRON_CFG = 0, the PWRON signal is high and VIN > UVDET, the PMIC will turn on; the interrupt and sense bits, PWRONI and PWRONS respectively, will be set. • If PWRON_CFG = 1, VIN > UVDET and PWRON transitions from high to low, the PMIC will turn on; the interrupt and sense bits, PWRONI and PWRONS respectively, will be set. The sense bit will show the real time status of the PWRON pin. In this configuration, the PWRON input can be a mechanical switch debounced through a programmable debouncer, PWRONDBNC[1:0], to avoid a response to a very short (i.e., unintentional) key press. The interrupt is generated for both the falling and the rising edge of the PWRON pin. By default, a 30 ms interrupt debounce is applied to both falling and rising edges. The falling edge debounce timing can be extended with PWRONDBNC[1:0] as defined in the table below. The interrupt is cleared by software, or when cycling through the OFF mode. Table 25. PWRON Hardware Debounce Bit Settings Bits PWRONDBNC[1:0] State Turn On Debounce (ms) Falling Edge INT Debounce (ms) Rising Edge INT Debounce (ms) 00 0.0 31.25 31.25 01 31.25 31.25 31.25 10 125 125 31.25 11 750 750 31.25 Notes 37. The sense bit, PWRONS, is not debounced and follows the state of the PWRON pin. 6.4.2.2 Turn Off Events PWRON Pin The PWRON pin is used to power off the PF0200. The PWRON pin can be configured with OTP to power off the PMIC under the following two conditions: 1. PWRON_CFG bit = 0, SWxOMODE bit = 0 and PWRON pin is low. 2. PWRON_CFG bit = 1, SWxOMODE bit = 0, PWRONRSTEN = 1 and PWRON is held low for longer than 4.0 seconds. Alternatively, the system can be configured to restart automatically by setting the RESTARTEN bit. Thermal Protection If the die temperature surpasses a given threshold, the thermal protection circuit will power off the PMIC to avoid damage. A turn-on event will not power on the PMIC while it is in thermal protection. The part will remain in Off mode until the die temperature decreases below a given threshold. There are no specific interrupts related to this other than the warning interrupt. See Power Dissipation section for more detailed information. Undervoltage Detection When the voltage at VIN drops below the undervoltage falling threshold, UVDET, the state machine will transition to the Coin Cell mode. PF0200 Analog Integrated Circuit Device Data Freescale Semiconductor 29 FUNCTIONAL BLOCK REQUIREMENTS AND BEHAVIORS POWER GENERATION 6.4.3 Power Tree The PF0200 PMIC features four buck regulators, one boost regulator, six general purpose LDOs, one switch/LDO combination, and a DDR voltage reference to supply voltages for the application processor and peripheral devices. The buck regulators as well as the boost regulator are supplied directly from the main input supply (VIN). The inputs to all of the buck regulators must be tied to VIN, whether they are powered on or off. The six general use LDO regulators are directly supplied from the main input supply or from the switching regulators depending on the application requirements. Since VREFDDR is intended to provide DDR memory reference voltage, it should be supplied by any rail supplying voltage to DDR memories; the typical application recommends the use of SW3 as the input supply for VREFDDR. VSNVS is supplied by either the main input supply or the coin cell. Refer to Table 26 for a summary of all power supplies provided by the PF0200. Table 26.

Current rating per independent phase, when SW3A/B is set in single phase, current capability is up to 2500 mA. Figure 9 shows a simplified power map with various recommended options to supply the different block within the PF0200, as well as the typical application voltage domain on the i.MX 6 application processors. Note that each application power tree is dependent upon the system’s voltage and current requirements, therefore a proper input voltage should be selected for the regulators. The minimum operating voltage for the main VIN supply is 2.8 V, for lower voltages proper operation is not guaranteed. However at initial power up, the input voltage must surpass the rising UVDET threshold before proper operation is guaranteed. Refer to the representative tables and text specifying each supply for information on performance metrics and operating ranges. Table 27 summarizes the UVDET thresholds. Table 27.

PF0200 Typical Power Map PF0200 Analog Integrated Circuit Device Data Freescale Semiconductor 31 FUNCTIONAL BLOCK REQUIREMENTS AND BEHAVIORS POWER GENERATION 6.4.4 Buck Regulators Each buck regulator is capable of operating in PFM, APS, and PWM switching modes. 6.4.4.1 Current Limit Each buck regulator has a programmable current limit. In an overcurrent condition, the current is limited cycle-by-cycle. If the current limit condition persists for more than 8.0 ms, a fault interrupt is generated. 6.4.4.2 General Control To improve system efficiency the buck regulators can operate in different switching modes. Changing between switching modes can occur by any of the following means: I2C programming, exiting/entering the Standby mode, exiting/entering Sleep mode, and load current variation. Available switching modes for buck regulators are presented in Table 28. Table 28. Switching Mode Description Mode Description OFF The regulator is switched off and the output voltage is discharged. PFM In this mode, the regulator is always in PFM mode, which is useful at light loads for optimized efficiency. PWM In this mode, the regulator is always in PWM mode operation regardless of load conditions. APS In this mode, the regulator moves automatically between pulse skipping mode and PWM mode depending on load conditions. During soft-start of the buck regulators, the controller transitions through the PFM, APS, and PWM switching modes. 3.0 ms (typical) after the output voltage reaches regulation, the controller transitions to the selected switching mode. Depending on the particular switching mode selected, additional ripple may be observed on the output voltage rail as the controller transitions between switching modes. Table 29 summarizes the Buck regulator programmability for Normal and Standby modes. Table 29. Regulator Mode Control SWxMODE[3:0] Normal Mode Standby Mode 0000 Off Off 0001 PWM Off 0010 Reserved Reserved 0011 PFM Off 0100 APS Off 0101 PWM PWM 0110 PWM APS 0111 Reserved Reserved 1000 APS APS 1001 Reserved Reserved 1010 Reserved Reserved 1011 Reserved Reserved 1100 APS PFM 1101 PWM PFM 1110 Reserved Reserved 1111 Reserved Reserved Transitioning between Normal and Standby modes can affect a change in switching modes as well as output voltage. The rate of the output voltage change is controlled by the Dynamic Voltage Scaling (DVS), explained in Dynamic Voltage Scaling. The output voltage options are the same for Normal and Standby modes for each regulator. PF0200 32 Analog Integrated Circuit Device Data Freescale Semiconductor FUNCTIONAL BLOCK REQUIREMENTS AND BEHAVIORS POWER GENERATION When in Standby mode, the regulator outputs the voltage programmed in its standby voltage register and will operate in the mode selected by the SWxMODE[3:0] bits. Upon exiting Standby mode, the regulator will return to its normal switching mode and its output voltage programmed in its voltage register. Any regulators whose SWxOMODE bit is set to “1” will enter Sleep mode if a PWRON turn-off event occurs, and any regulator whose SWxOMODE bit is set to “0” will be turned off. In Sleep mode, the regulator outputs the voltage programmed in its off (Sleep) voltage register and operates in the PFM mode. The regulator will exit the Sleep mode when a turn-on event occurs. Any regulator whose SWxOMODE bit is set to “1” will remain on and change to its normal configuration settings when exiting the Sleep state to the ON state. Any regulator whose SWxOMODE bit is set to “0” will be powered up with the same delay in the start-up sequence as when powering On from Off. At this point, the regulator returns to its default ON state output voltage and switch mode settings. Table 23 shows the control bits in Sleep mode. When Sleep mode is activated by the SWxOMODE bit, the regulator will use the set point as programmed by SW1ABOFF[5:0] for SW1A/B and by SWxOFF[6:0] for SW2 and SW3A/B. Dynamic Voltage Scaling To reduce overall power consumption, processor core voltages can be varied depending on the mode or activity level of the processor. 1. Normal operation: The output voltage is selected by I2C bits SW1AB[5:0] for SW1A/B and SWx[6:0] for SW2 and SW3A/B. A voltage transition initiated by I2C is governed by the DVS stepping rates shown in Table 32 and Table 33. 2. Standby Mode: The output voltage can be higher, or lower than in normal operation, but is typically selected to be the lowest state retention voltage of a given processor; it is selected by I2C bits SW1ABSTBY[5:0] for SW1A/B and by bits SWxSTBY[6:0] for SW2 and SW3A/B. Voltage transitions initiated by a Standby event are governed by the SW1ABDVSSPEED[1:0] and SWxDVSSPEED[1:0] I2C bits shown in Table 32 and Table 33, respectively. 3. Sleep Mode: The output voltage can be higher or lower than in normal operation, but is typically selected to be the lowest state retention voltage of a given processor; it is selected by I2C bits SW1ABOFF[5:0] for SW1A/B and by bits SWxOFF[6:0] for SW2, and SW3A/B. Voltage transitions initiated by a turn-off event are governed by the SW1ABDVSSPEED[1:0] and SWxDVSSPEED[1:0] I2C bits shown in Table 32 and Table 33, respectively. Table 30, Table 31, Table 32, and Table 33 summarize the set point control and DVS time stepping applied to all regulators. Table 30.

However, if the regulators are programmed in PFM or APS mode during a DVS transition, the falling slope can be influenced by the load. Additionally, as the current capability in PFM mode is reduced, controlled DVS transitions in PFM mode could be affected. Critically timed DVS transitions are best assured with PWM mode operation. The following diagram shows the general behavior for the regulators when initiated with I2C programming, or standby control. During the DVS period the overcurrent condition on the regulator should be masked.

Voltage Stepping with DVS Regulator Phase Clock The SWxPHASE[1:0] bits select the phase of the regulator clock as shown in Table 34. By default, each regulator is initialized at 90 ° out of phase with respect to each other. For example, SW1A/B is set to 0 °, SW2 is set to 90 ° and SW3A/B is set to 180 ° by default at power up. Table 34. Regulator Phase Clock Selection SWxPHASE[1:0] Phase of Clock Sent to Regulator (degrees) 00 0 01 90 10 180 11 270 The SWxFREQ[1:0] register is used to set the desired switching frequency for each one of the buck regulators. Table 36 shows the selectable options for SWxFREQ[1:0]. For each frequency, all phases will be available, this allows regulators operating at different frequencies to have different relative switching phases. However, not all combinations are practical. For example, 2.0 MHz, 90 ° and 4.0 MHz, 180 ° are the same in terms of phasing. Table 35 shows the optimum phasing when using more than one switching frequency.

Regulator Frequency Configuration SWxFREQ[1:0] Frequency 00 1.0 MHz 01 2.0 MHz 10 4.0 MHz 11 Reserved Programmable Maximum Current The maximum current, ISWxMAX, of each buck regulator is programmable. This allows the use of smaller inductors where lower currents are required. Programmability is accomplished by choosing the number of paralleled power stages in each regulator. The SWx_PWRSTG[2:0] bits on the Extended Page 2 of the register map control the number of power stages. See Table 37 for the programmable options.

SW2 Block Diagram SW2 Setup and Control Registers SW2 output voltage is programmable from 0.400 to 3.300 V; however, bit SW2[6] in register SW2VOLT is read-only during normal operation. Its value is determined by the default configuration, or may be changed by using the OTP registers. Therefore, once SW2[6] is set to “0”, the output will be limited to the lower output voltages from 0.400 to 1.975 V with 25 mV increments, as determined by bits SW2[5:0]. Likewise, once bit SW2[6] is set to “1”, the output voltage will be limited to the higher output voltage range from 0.800 to 3.300 V with 50 mV increments, as determined by bits SW2[5:0]. In order to optimize the performance of the regulator, it is recommended that only voltages from 2.000 to 3.300 V be used in the high range, and the lower range be used for voltages from 0.400 to 1.975 V. The output voltage set point is independently programmed for Normal, Standby, and Sleep mode by setting the SW2[5:0], SW2STBY[5:0] and SW2OFF[5:0] bits, respectively. However, the initial state of bit SW2[6] will be copied into bits SW2STBY[6], and SW2OFF[6] bits. Therefore, the output voltage range will remain the same in all three operating modes.

Table 28 describes the available switching modes and Table 29 show the actual configuration options for the SW3xMODE[3:0] bits. SW3A/B can be configured in various phasing schemes, depending on the desired cost/performance trade-offs. The following configurations are available: • A single phase • Independent regulators The desired configuration is programmed in OTP by using the SW3_CONFIG[1:0] bits.Table 57 shows the options for the SW3CFG[1:0] bits. Table 57. SW3 Configuration SW3_CONFIG[1:0] Description 00 A/B Single Phase 01 A/B Single Phase 10 Reserved 11 A/B Independent SW3A/B Single Phase In this configuration, SW3ALX and SW3BLX are connected in single phase with a single inductor a shown in Figure 15. This configuration reduces cost and component count. Feedback is taken from the SW3AFB pin and the SW3BFB pin must be left open. Although control is from SW3A, registers of both regulators, SW3A and SW3B, must be identically set.

SW3A/B Independent Output Block Diagram SW3A/B Setup and Control Registers SW3A/B output voltage is programmable from 0.400 to 3.300 V; however, bit SW3x[6] in register SW3xVOLT is read-only during normal operation. Its value is determined by the default configuration, or may be changed by using the OTP registers. Therefore, once SW3x[6] is set to “0”, the output will be limited to the lower output voltages from 0.40 to 1.975 V with 25 mV increments, as determined by bits SW3x[5:0]. Likewise, once bit SW3x[6] is set to "1", the output voltage will be limited to the higher output voltage range from 0.800 to 3.300 V with 50 mV increments, as determined by bits SW3x[5:0]. In order to optimize the performance of the regulator, it is recommended that only voltages from 2.00 to 3.300 V be used in the high range and that that the lower range be used for voltages from 0.400 to 1.975 V. The output voltage set point is independently programmed for Normal, Standby, and Sleep mode by setting the SW3x[5:0], SW3xSTBY[5:0], and SW3xOFF[5:0] bits respectively; however, the initial state of the SW3x[6] bit will be copied into the SW3xSTBY[6] and SW3xOFF[6] bits. Therefore, the output voltage range will remain the same on all three operating modes. Table 58 shows the output voltage coding valid for SW3x. Note: Output voltages of 0.6 V and below are not supported.

SWBST can supply the VUSB regulator for the USB PHY in OTG mode, as well as the VBUS voltage. Note that the parasitic leakage path for a boost regulator will cause the SWBSTOUT and SWBSTFB voltage to be a Schottky drop below the input voltage whenever SWBST is disabled. The switching NMOS transistor is integrated on-chip. Figure 18 shows the block diagram and component connection for the boost regulator.

Refer to Bias and References Block Description section for further information on the internal reference voltages. A Low Power mode is automatically activated by reducing bias currents when the load current is less than I_Lmax/5. However, the lowest bias currents may be attained by forcing the part into its Low Power mode by setting the VGENxLPWR bit. The use of this bit is only recommended when the load is expected to be less than I_Lmax/50, otherwise performance may be degraded. When a regulator is disabled, the output will be discharged by an internal pull-down. The pull-down is also activated when RESETBMCU is low.

Transient Waveforms PF0200 Analog Integrated Circuit Device Data Freescale Semiconductor 61 FUNCTIONAL BLOCK REQUIREMENTS AND BEHAVIORS POWER GENERATION 6.4.6.2 Short-circuit Protection All general purpose LDOs have short-circuit protection capability. The Short-circuit Protection (SCP) system includes debounced fault condition detection, regulator shutdown, and processor interrupt generation, to contain failures and minimize the chance of product damage. If a short-circuit condition is detected, the LDO will be disabled by resetting its VGENxEN bit, while at the same time, an interrupt VGENxFAULTI will be generated to flag the fault to the system processor. The VGENxFAULTI interrupt is maskable through the VGENxFAULTM mask bit. The SCP feature is enabled by setting the REGSCPEN bit. If this bit is not set, the regulators will not automatically be disabled upon a short-circuit detection. However, the current limiter will continue to limit the output current of the regulator. By default, the REGSCPEN is not set; therefore, at start-up none of the regulators will be disabled if an overloaded condition occurs. A fault interrupt, VGENxFAULTI, will be generated in an overload condition regardless of the state of the REGSCPEN bit. See Table 75 for SCP behavior configuration. Table 75. Short-circuit Behavior 6.4.6.3 REGSCPEN[0] Short-circuit Behavior 0 Current limit 1 Shutdown LDO Regulator Control Each LDO is fully controlled through its respective VGENxCTL register. This register enables the user to set the LDO output voltage according to Table 76 for VGEN1 and VGEN2; and uses the voltage set point on Table 77 for VGEN3 through VGEN6. Table 76.

Each regulator has associated I2C bits for this. Table 78 presents a summary of all valid combinations of the control bits on VGENxCTL register and the expected behavior of the LDO output. Table 78.

When the LDO Output voltage is set above 2.6 V the minimum allowed input voltage need to be at least the output voltage plus 0.25 V for proper regulation due to the dropout voltage generated through the internal LDO transistor. 66. The PSRR of the regulators is measured with the perturbing signal at the input of the regulator. The power management IC is supplied separately from the input of the regulator and does not contain the perturbed signal. During measurements, care must be taken not to operate in the dropout region of the regulator under test. VIN3MIN refers to the minimum allowed input voltage for a particular output voltage. 6.4.7 VSNVS LDO/Switch VSNVS powers the low power, SNVS/RTC domain on the processor. It derives its power from either VIN, or coin cell, and cannot be disabled. When powered by both, VIN takes precedence when above the appropriate comparator threshold. When powered by VIN, VSNVS is an LDO capable of supplying seven voltages: 3.0, 1.8, 1.5, 1.3, 1.2, 1.1, and 1.0 V. The bits VSNVSVOLT[2:0] in register VSNVS_CONTROL determine the output voltage. When powered by coin cell, VSNVS is an LDO capable of supplying 1.8, 1.5, 1.3, 1.2, 1.1, or 1.0 V as shown in Table 92. If the 3.0 V option is chosen with the coin cell, VSNVS tracks the coin cell voltage by means of a switch, whose maximum resistance is 100 . In this case, the VSNVS voltage is simply the coin cell voltage minus the voltage drop across the switch, which is 40 mV at a rated maximum load current of 400 A. The default setting of the VSNVSVOLT[2:0] is 110, or 3.0 V, unless programmed otherwise in OTP. However, when the coin cell is applied for the very first time, VSNVS will output 1.0 V. Only when VIN is applied thereafter will VSNVS transition to its default, or programmed value if different. Upon subsequent removal of VIN, with the coin cell attached, VSNVS will change configuration from an LDO to a switch for the “110” setting, and will remain as an LDO for the other settings, continuing to output the same voltages as when VIN is applied, providing certain conditions are met as described in Table 92.

If the voltage at VIN goes below the VIN threshold (VTL1 and VTL0), contact-bounced, or removed, the coin cell maintained logic will be powered by the voltage applied to LICELL. The supply for internal logic and the VSNVS rail will switch over to the LICELL pin when VIN goes below VTL1 or VTL0, even in the absence of a voltage at the LICELL pin, resulting in clearing of memory and turning off of VSNVS. When system operation below VTL1 is required, for systems not utilizing a coin cell, connect the LICELL pin to any system voltage between 1.8 and 3.0 V. A small capacitor should be placed from LICELL to ground under all circumstances. PF0200 Analog Integrated Circuit Device Data Freescale Semiconductor 79 FUNCTIONAL BLOCK REQUIREMENTS AND BEHAVIORS POWER GENERATION Coin Cell Charger Control The coin cell charger circuit will function as a current-limited voltage source, resulting in the CC/CV taper characteristic typically used for rechargeable Lithium-Ion batteries. The coin cell charger is enabled via the COINCHEN bit while the coin cell voltage is programmable through the VCOIN[2:0] bits on register COINCTL on Table 97. The coin cell charger voltage is programmable. In the ON state, the charger current is fixed at ICOINHI. In Sleep and Standby modes, the charger current is reduced to a typical 10 A. In the OFF state, coin cell charging is not available as the main battery could be depleted unnecessarily. The coin cell charging will be stopped when VIN is below UVDET. Table 96.

Coin Cell Charger Specifications Parameter PF0200 80 Analog Integrated Circuit Device Data Freescale Semiconductor FUNCTIONAL BLOCK REQUIREMENTS AND BEHAVIORS CONTROL INTERFACE I2C BLOCK DESCRIPTION Control Interface I2C Block Description 6.5 The PF0200 contains an I2C interface port which allows access by a processor, or any I2C master, to the register set. Via these registers the resources of the IC can be controlled. The registers also provide status information about how the IC is operating. The SCL and SDA lines should be routed away from noisy signals and planes to minimize noise pick up. To prevent reflections in the SCL and SDA traces from creating false pulses, the rise and fall times of the SCL and SDA signals must be greater than 20 ns. This can be accomplished by reducing the drive strength of the I2C master via software. The i.MX6 I2C driver defaults to a 40 ohm drive strength. It is recommended to use a drive strength of 80 ohm or higher to increase the edge times. Alternatively, this can be accomplished by using small capacitors from SCL and SDA to ground. For example, use 5.1 pF capacitors from SCL and SDA to ground for bus pull-up resistors of 4.8 kohm. PWRON must be logic high for I2C communication to work robustly. 6.5.1 I2C Device ID I2C interface protocol requires a device ID for addressing the target IC on a multi-device bus. To allow flexibility in addressing for bus conflict avoidance, fuse programmability is provided to allow configuration for the lower 3 address LSB(s). Refer to One Time Programmability (OTP) for more details. This product supports 7-bit addressing only; support is not provided for 10-bit or general call addressing. Note, when the TBB bits for the I2C slave address are written, the next access to the chip, must then use the new slave address; these bits take affect right away. 6.5.2 I2C Operation The I2C mode of the interface is implemented generally following the Fast mode definition which supports up to 400 kbits/s operation (exceptions to the standard are noted to be 7-bit only addressing and no support for General Call addressing.) Timing diagrams, electrical specifications, and further details can be found in the I2C specification, which is available for download at: http://www.nxp.com/acrobat_download/literature/9398/39340011.pdf I2C read operations are also performed in byte increments separated by an ACK. Read operations also begin with the MSB and each byte will be sent out unless a STOP command or NACK is received prior to completion. The following examples show how to write and read data to and from the IC. The host initiates and terminates all communication. The host sends a master command packet after driving the start condition. The device will respond to the host if the master command packet contains the corresponding slave address. In the following examples, the device is shown always responding with an ACK to transmissions from the host. If at any time a NACK is received, the host should terminate the current transaction and retry the transaction.

I2C Read Example PF0200 Analog Integrated Circuit Device Data Freescale Semiconductor 81 FUNCTIONAL BLOCK REQUIREMENTS AND BEHAVIORS CONTROL INTERFACE I2C BLOCK DESCRIPTION 6.5.3 Interrupt Handling The system is informed about important events based on interrupts. Unmasked interrupt events are signaled to the processor by driving the INTB pin low. Each interrupt is latched so that even if the interrupt source becomes inactive, the interrupt will remain set until cleared. Each interrupt can be cleared by writing a “1” to the appropriate bit in the Interrupt Status register; this will also cause the INTB pin to go high. If there are multiple interrupt bits set the INTB pin will remain low until all are either masked or cleared. If a new interrupt occurs while the processor clears an existing interrupt bit, the INTB pin will remain low. Each interrupt can be masked by setting the corresponding mask bit to a 1. As a result, when a masked interrupt bit goes high, the INTB pin will not go low. A masked interrupt can still be read from the Interrupt Status register. This gives the processor the option of polling for status from the IC. The IC powers up with all interrupts masked, so the processor must initially poll the device to determine if any interrupts are active. Alternatively, the processor can unmask the interrupt bits of interest. If a masked interrupt bit was already high, the INTB pin will go low after unmasking. The sense registers contain status and input sense bits so the system processor can poll the current state of interrupt sources. They are read only, and not latched or clearable. Interrupts generated by external events are debounced; therefore, the event needs to be stable throughout the debounce period before an interrupt is generated. Nominal debounce periods for each event are documented in the INT summary Table 100 . Due to the asynchronous nature of the debounce timer, the effective debounce time can vary slightly. 6.5.4 Interrupt Bit Summary Table 100 summarizes all interrupt, mask, and sense bits associated with INTB control.

The data written to MEMA[7:0], MEMB[7:0], MEMC[7:0], and MEMD[7:0] is maintained by the coin cell when the main battery is deeply discharged, removed, or contact-bounced. The contents of the embedded memory are reset by COINPORB. The banks can be used for any system need for bit retention with coin cell backup. Table 116.

Register MEMD ADDR 0x1F Name MEMD 6.5.6 Bit # R/W Default 7:0 R/W 0 Description Memory bank D Register Bitmap The register map is comprised of thirty-two pages, and its address and data fields are each eight bits wide. Only the first two pages can be accessed. On each page, registers 0 to 0x7F are referred to as 'functional', and registers 0x80 to 0xFF as 'extended'. On each page, the functional registers are the same, but the extended registers are different. To access registers on Extended Page 1, one must first write 0x01 to the page register at address 0x7F, and to access registers Extended Page 2, one must first write 0x02 to the page register at address 0x7F. To access the Functional Page from one of the extended pages, no write to the page register is necessary. Registers that are missing in the sequence are reserved; reading from them will return a value 0x00, and writing to them will have no effect. The contents of all registers are given in the tables defined in this chapter; each table is structure as follows: Name: Name of the bit. Bit #: The bit location in the register (7-0) R/W: Read / Write access and control • R is read-only access • R/W is read and write access • RW1C is read and write access with write 1 to clear Reset: Reset signals are color coded based on the following legend. Bits reset by SC and VCOREDIG_PORB Bits reset by PWRON or loaded default or OTP configuration Bits reset by DIGRESETB Bits reset by PORB or RESETBMCU Bits reset by VCOREDIG_PORB Bits reset by POR or OFFB Default: The value after reset, as noted in the Default column of the memory map. • Fixed defaults are explicitly declared as 0 or 1. • “X” corresponds to Read / Write bits that are initialized at start-up, based on the OTP fuse settings or default if VDDOTP = 1.5 V. Bits are subsequently I2C modifiable, when their reset has been released. “X” may also refer to bits that may have other dependencies. For example, some bits may depend on the version of the IC, or a value from an analog block, for instance the sense bits for the interrupts.

Freescale does not assume liability, endorse, or warrant components from external manufacturers that are referenced in circuit drawings or tables. While Freescale offers component recommendations in this configuration, it is the customer’s responsibility to validate their application. 7.2 PF0200 Layout Guidelines 7.2.1 General Board Recommendations 1. It is recommended to use an eight layer board stack-up arranged as follows: • High current signal • GND • Signal • Power • Power • Signal • GND • High current signal 2. Allocate TOP and BOTTOM PCB Layers for POWER ROUTING (high-current signals), copper-pour the unused area. 3. Use internal layers sandwiched between two GND planes for the SIGNAL routing. 7.2.2 Component Placement It is desirable to keep all component related to the power stage as close to the PMIC as possible, specially decoupling input and output capacitors. 7.2.3 General Routing Requirements 1. Some recommended things to keep in mind for manufacturability: • Via in pads require a 4.5 mil minimum annular ring. Pad must be 9.0 mils larger than the hole • Maximum copper thickness for lines less than 5.0 mils wide is 0.6 oz copper • Minimum allowed spacing between line and hole pad is 3.5 mils PF0200 Analog Integrated Circuit Device Data Freescale Semiconductor 101 TYPICAL APPLICATIONS PF0200 LAYOUT GUIDELINES • Minimum allowed spacing between line and line is 3.0 mils 2. Care must be taken with SWxFB pins traces. These signals are susceptible to noise and must be routed far away from power, clock, or high power signals, like the ones on the SWxIN, SWx, SWxLX, SWBSTIN, SWBST, and SWBSTLX pins. They could be also shielded. 3. Shield feedback traces of the regulators and keep them as short as possible (trace them on the bottom so the ground and power planes shield these traces). 4. Avoid coupling traces between important signal/low noise supplies (like REFCORE, VCORE, VCOREDIG) from any switching node (i.e. SW1ALX, SW1BLX, SW2LX, SW3ALX, SW3BLX, and SWBSTLX). 5. Make sure that all components related to a specific block are referenced to the corresponding ground. 7.2.4 Parallel Routing Requirements 1. I2C signal routing • CLK is the fastest signal of the system, so it must be given special care. • To avoid contamination of these delicate signals by nearby high power or high frequency signals, it is a good practice to shield them with ground planes placed on adjacent layers. Make sure the ground plane is uniform throughout the whole signal trace length. Figure 25. Recommended Shielding for Critical Signals • • 7.2.5 These signals can be placed on an outer layer of the board to reduce their capacitance with respect to the ground plane. Care must be taken with these signals not to contaminate analog signals, as they are high frequency signals. Another good practice is to trace them perpendicularly on different layers, so there is a minimum area of proximity between signals. Switching Regulator Layout Recommendations 1. Per design, the switching regulators in PF0200 are designed to operate with only one input bulk capacitor. However, it is recommended to add a high-frequency filter input capacitor (CIN_hf), to filter out any noise at the regulator input. This capacitor should be in the range of 100 nF and should be placed right next to or under the IC, closest to the IC pins. 2. Make high-current ripple traces low-inductance (short, high W/L ratio). 3. Make high-current traces wide or copper islands.

Junction to Ambient Thermal Resistance Nomenclature: the JEDEC specification reserves the symbol RθJA or θJA (Theta-JA) strictly for junction-to-ambient thermal resistance on a 1s test board in natural convection environment. RθJMA or θJMA (Theta-JMA) will be used for both junction-to-ambient on a 2s2p test board in natural convection and for junction-to-ambient with forced convection on both 1s and 2s2p test boards. It is anticipated that the generic name, Theta-JA, will continue to be commonly used. The JEDEC standards can be consulted at http://www.jedec.org. PF0200 Analog Integrated Circuit Device Data Freescale Semiconductor 103 TYPICAL APPLICATIONS THERMAL INFORMATION 7.3.2 Estimation of Junction Temperature An estimation of the chip junction temperature TJ can be obtained from the equation: TJ = TA + (RθJA x PD) with: TA = Ambient temperature for the package in °C RJA = Junction to ambient thermal resistance in °C/W PD = Power dissipation in the package in W The junction to ambient thermal resistance is an industry standard value that provides a quick and easy estimation of thermal performance. Unfortunately, there are two values in common usage: the value determined on a single layer board RθJA and the value obtained on a four layer board RθJMA. Actual application PCBs show a performance close to the simulated four layer board value although this may be somewhat degraded in case of significant power dissipated by other components placed close to the device. At a known board temperature, the junction temperature TJ is estimated using the following equation TJ = TB + (RθJB x PD) with TB = Board temperature at the package perimeter in °C RθJB = Junction to board thermal resistance in °C/W PD = Power dissipation in the package in W When the heat loss from the package case to the air can be ignored, acceptable predictions of junction temperature can be made.
