GENERAL DESCRIPTION The PAC5253 belongs to Active-Semi's broad portfolio of full-featured Power Application Controller TM (PAC) products that are highly optimized for controlling and powering next generation smart energy appliances, devices, and equipment. These application controllers integrate a 50MHz ARM ® CortexTM-M0 32-bit microcontroller core with Active-Semi's proprietary and patent-pending Multi-Mode Power Manager TM, Configurable Analog Front EndTM, and Application Specific Power DriversTM to form the most compact microcontroller-based power and general purpose application systems ranging from digital power supply to motor control. The PAC52xx microcontroller features up to 32kB of embedded FLASH and 8kB of SRAM memory, a high-speed 10-bit 1µs analog-to-digital converter (ADC) with dual auto-sampling sequencers, 5V/3.3V I/Os, flexible clock sources, timers, a versatile 14-channel PWM engine, and several serial interfaces. The Multi-Mode Power Manager (MMPM) provides “all-in-one” efficient power management solution for multiple types of power sources. It features a configurable multi-mode switching supply controller capable of operating in buck, flyback, or boost mode, and up to four linear regulated voltage supplies. The Application Specific Power Drivers (ASPD) are highvoltage and ultra-high-voltage power drivers designed for each target set of control applications, including half bridge, Hbridge, 3-phase, intelligent power module (IPM), and general purpose driving. The Configurable Analog Front End (CAFE) comprises differential programmable gain amplifiers, single-ended programmable gain amplifiers, comparators, digital-toanalog converters, and I/Os for programmable and inter-connectible signal sampling, feedback amplification, and sensor monitoring of multiple analog input signals. Together, these modules and microcontroller enable a wide range of compact applications with highly integrated power management, driving, feedback, and control for DC supply up to 52V and for line AC supply.

Functional Description The Multi-Mode Power Manager (Figure 10-1) is optimized to efficiently provide "all-in-one" power management required by the PAC and associated application circuitry from a wide range of input power sources. It incorporates a dedicated multimode switching supply (MMSS) controller operable as a buck, flyback, or boost converter to efficiently convert power from a DC or AC input source to generate a main supply output V P. Four linear regulators provide VSYS, VCCIO, VCC33, and VCC18 supplies for 5V system, 5V or 3.3V I/O, 3.3V mixed signal, and 1.8V microcontroller core circuitry. The power manager also handles system functions including internal reference generation, timers, hibernate mode management, and power and temperature monitoring. 10.3.1. Multi-Mode Switching Supply (MMSS) Controller The MMSS controller drives an external power transistor for pulse-width modulation switching of an inductor or transformer for power conversion. The DRM output drives the gate of the n-channel MOSFET or the base of the NPN between the VHM on state and VSS off state at proper duty cycle and switching frequency to ensure that the main supply voltage VP is regulated. The VP regulation voltage is initially set to 15V during start up, and can be reconfigured to be 5V, - 19 - Rev 1.10‒August 4, 2015 PAC5253 Power Application Controller 9V, or 12V by the microcontroller after initialization. 1 When VP is lower than the target regulation voltage, the internal feedback control circuitry causes the inductor current to increase to raise V P. Conversely, when VP is higher than the regulation voltage, the feedback loop control causes the inductor current to decrease to lower V P. The feedback loop is internally stabilized. The output current capability of the switching supply is determined by the external current sense resistor. In the high-side current sense buck mode, the inductor current signal is sensed differentially between the CSM pin and VP, and has a peak current limit threshold of 0.26V. In the low-side current sense flyback or boost mode, the inductor current signal is sensed differentially between the CSM pin and V SS, and has a peak current limit threshold of 1V. The MMSS controller is flexible and configurable as a buck, flyback, or boost converter. Input sources include battery supply for buck mode (Figure 10-2), and AC line supply voltage range for ultra-high-voltage buck mode (Figure 10-3), AC/DC flyback mode (Figure 10-4). The MMSS controller operational mode is determined by external configuration and register setting from the microcontroller after power up. It can operate in either high-side or low-side current sense mode, and does not require external feedback loop compensation circuitry. For optional extended application range, the MMSS also incorporates additional digital control by the microcontroller to add accurate computations for outer feedback loop control such as power factor correction and accurate current control.

AC/DC Flyback Mode VHM VAC (120V/230V) PAC5253 VP DRM CSM VP (15V default) The MMSS detects and selects between high-side and low-side mode during start up based on the placement of the current sense resistor and the CSM pin voltage. It employs a safe start up mode with 9.5kHz switching frequency until V P exceeds 4.3V under-voltage-lockout threshold, then transitions to the 45kHz default switching frequency for at least 6ms to bring V P close to the target voltage, before enabling the linear regulators. Any extra load should only be applied after the supplies are available and the microprocessor has initialized. The switching frequency can be reconfigured by the microprocessor to be 181kHz to 500kHz in the high switching frequency mode for battery-based applications, and to be 45kHz to 125kHz in the low switching frequency mode for AC applications. Upon initialization, the microcontroller must reconfigure the MMSS to the desired settings for V P regulation voltage, switching mode, switching frequency, and V HM clamp. Refer to the PAC application notes and user guide for MMSS controller design and programming. If a stable external 5V to 15V power source is available, it can power the V P main supply and all the linear regulators directly without requiring the MMSS controller to operate. In such applications, V HM can be connected directly to VP and the microcontroller should disable the MMSS upon initialization to reduce power loss. 10.3.2. Linear Regulators The MMPM includes up to four linear regulators. The system supply regulator is a medium voltage regulator that takes the VP supply and sources up to 200mA at REGO until V SYS, externally coupled to REGO, reaches 5V. This allows a properly rated external resistor to be connected from REGO to V SYS to close the current loop and offload power dissipation between VP and VSYS. Once VSYS is above 4V, the three additional 40mA linear regulators for V CCIO, VCC33, and VCC18 supplies sequentially power up. Figure 10-5 shows typical circuit connections for the linear regulators. For 5V I/O systems, short the VCCIO pin to VSYS to bypass the VCCIO regulator. For 3.3V I/O systems, the VCCIO regulator generates 3.3V. The VCC33 and VCC18 regulators generate 3.3V and 1.8V, respectively. When V SYS, VCCIO, VCC33, and VCC18 are all above their respective power good threshold, and the configurable power on reset duration has expired, the microcontroller is initialized. - 21 - Rev 1.10‒August 4, 2015 PAC5253 Power Application Controller Figure 10-5.

Connect instead to a 4.7µF capacitor for 3.3V I/O. 10.3.3. Power Up Sequence The MMPM follows a typical power up sequence as in the Figure 10-6 below. A typical sequence begins with input power supply being applied, followed by the safe start up and start up durations to bring the switching supply output V P to 15V, before the linear regulators are enabled. When all the supplies are ready, the internal clocks become available, and the microcontroller starts executing from the program memory. During initialization, the microcontroller can reconfigure the switching supply to a different VP regulation voltage such as 15V and to an appropriate switching frequency and switching mode. The total loading on the switching supply must be kept below 25% of the maximum output current until after the reconfiguration of the switching supply is complete. For AC input supply applications, the start up sequence includes an additional charging time for VHM depending on the start-up resistor and capacitor values. Figure 10-6.

Hibernate Mode The IC can go into an ultra-low power hibernate mode via the microcontroller firmware or via the optional push button (PBTN, see Push Button description in Configurable Analog Front End). In hibernate mode, only a minimal amount (typically 18µA) of current is used by VHM, and the MMSS controller and all internal regulators are shut down to eliminate power drain from the output supplies. The system exits hibernate mode after a wake-up timer duration (configurable from 125ms to 8s or infinite) has expired or, if push button enabled, after an additional push button event has been detected. - 22 - Rev 1.10‒August 4, 2015 PAC5253 Power Application Controller When exiting the hibernate mode, the power manager goes through the start up cycle and the microcontroller is reinitialized. Only the persistent power manager status bits (resets and faults) are retained during hibernation. 10.3.5. Power and Temperature Monitor Whenever any of the VSYS, VCCIO, VCC33, or VCC18 power supplies falls below their respective power good threshold voltage, a fault event is detected and the microcontroller is reset. The microcontroller stays in the reset state until V SYS, VCCIO, VCC33, and VCC18 supply rails are all good again and the reset time has expired. A microcontroller reset can also be initiated by a maskable temperature fault event that occurs when the IC temperature reaches 170°C. The fault status bits are persistent during reset, and can be read by the microcontroller upon re-initialization to determine the cause of previous reset. A power monitoring signal VMON is provided onto the ADC pre-multiplexer for monitoring various internal power supplies. VMON can be set to be V CC18, 0.4•VCC33, 0.4•VCCIO, 0.4•VSYS, 0.1•VREGO, 0.1•VP, 0.0333•VHM, or the internal compensation voltage VCOMP for switching supply power monitoring. For power and temperature warning, a VP low event at 77% of the regulation voltage and an IC temperature warning event at 140°C are provided as maskable interrupts to the microcontroller. These warnings allow the microcontroller to safely power down the system. In addition to the temperature warning interrupt and fault reset, a temperature monitor signal VTEMP = 1.5 + 5.04e-3 • (T 25°C) (V) is provided onto the ADC pre-multiplexer for IC temperature measurement. 10.3.6. Voltage Reference The reference block includes a 2.5V high precision reference voltage that provides the 2.5V reference voltage for the ADC, the DACs, and the 4-level programmable threshold voltage VTHREF (0.1V, 0.2V, 0.5V, and 1.25V). - 23 - Rev 1.10‒August 4, 2015 PAC5253 Power Application Controller 10.4.

Functional Description The device includes a Configurable Analog Front End (CAFE, Figure 11-1) accessible through up to 10 analog and I/O pins. These pins can be configured to form flexible interconnected circuitry made up of up to 3 differential programmable gain amplifiers, 4 single-ended programmable gain amplifiers, 4 general purpose comparators, 3 phase comparators, 10 protection comparators, and one buffer output. These pins can also be programmed as analog feed-through pins, or as analog front end I/O pins that can function as digital inputs or digital open-drain outputs. The PAC proprietary configurable analog signal matrix (CASM) and configurable digital signal matrix (CDSM) allow real time asynchronous analog and digital signals to be routed in flexible circuit connections for different applications. A push button function is provided for optional push button on, hibernate, and off power management function. 11.2.1. Differential Programmable Gain Amplifier (DA) The DAxP and DAxN pin pair are positive and negative inputs, respectively, to a differential programmable gain amplifier. The differential gain can be programmable to be 1x, 2x, 4x, 8x, 16x, 32x, and 48x for zero ohm signal source impedance. The differential programmable gain amplifier has -0.3V to 3.5V input common mode range, and its output can be configured for routing directly to the ADC pre-multiplexer, or through a sample-and-hold circuit synchronized with the ADC auto-sampling mechanism. Each differential amplifier is accompanied by offset calibration circuitry, and two protection comparators for protection event monitoring. The programmable gain differential amplifier is optimized for use with signal source impedance lower than 500Ω and with matched source impedance on both positive and negative inputs for minimal offset. The effective gain is scaled by 13.5k / (13.5k + RSOURCE), where RSOURCE is the matched source impedance of each input. 11.2.2. Single-Ended Programmable Gain Amplifier (AMP) Each AMPx input goes to a single-ended programmable gain amplifier with signal relative to V SSA. The amplifier gain can be programmed to be 1x, 2x, 4x, 8x, 16x, 32x, and 48x, or as analog feed-through. The programmable gain amplifier output is routed via a multiplexer to the configurable analog signal matrix CASM. 11.2.3. General Purpose Comparator (CMP) The general purpose comparator takes the CMPx input and compares it to either the programmable threshold voltage (VTHREF) or a signal from the configurable analog signal matrix CASM. The comparator has 0V to V SYS input common mode range, and its polarity-selectable output is routed via a multiplexer to either a data input bit or the configurable digital signal matrix CDSM. Each general purpose comparator has two mask bits to prevent or allow rising or falling edge of its output to trigger second microcontroller interrupt INT2, where INT2 can be configured to activate protection event PR1. Each comparator output, routed via CASM and with 500ns de-glitch time, can also be configured to activate protection event PR1. 11.2.4. Phase Comparator (PHC) The phase comparator takes the PHCx input and compares it to either the programmable threshold voltage (V THREF) or a signal from the configurable analog signal matrix CASM. The comparison signal can be set to a phase reference signal generated by averaging the PHCx input voltages. In a three-phase motor control application, the phase reference signal acts as a virtual center tap for BEMF detection. The PHCx inputs are optionally fed through to the CASM. The phase comparator has 0V to VSYS input common mode range, and its polarity-selectable output is routed to a data input bit and to the phase/position multiplexer synchronized with the auto-sampling sequencers. 11.2.5. Protection Comparator (PCMP) Two protection comparators are provided in association with each differential programmable gain amplifier, with outputs available to trigger protection events and accessible as read-back output bits. The high-speed protection (HP) comparator compares the PCMPx pin to the 8-bit HP DAC output voltage, with full scale voltage of 2.5V. The limit protection (LP) comparator compares the differential programmable gain amplifier output to the 10-bit LP DAC output voltage, with full scale voltage of 2.5V. Each protection comparator has a mask bit to prevent or allow it to trigger the main microcontroller interrupt INT1. Each protection comparator also has one mask bit to prevent or allow it to activate protection event PR1, and another mask bit to - 29 - Rev 1.10‒August 4, 2015 PAC5253 Power Application Controller prevent or allow it to activate protection event PR2. These two protection events can be used directly by protection circuitry in the Application Specific Power Drivers (ASPD) to protect devices being driven. 11.2.6. Analog Output Buffer (BUF) A subset of the signals from the configurable analog signal matrix CASM can be multiplexed to the BUF6 pin for external use. The buffer offset voltage can be minimized with the built-in swap function. 11.2.7. Analog Front End I/O (AIO) Up to 10 AIOx pins are available in the device. In the analog front end I/O mode, the pin can be configured to be a digital input or digital open-drain output. The AIOx input or output signal can be set to a data input or output register bit, or multiplexed to one of the signals in the configurable digital signal matrix CDSM. The signal can be set to active high (default) or active low, with V SYS supply rail. Where AIO 6,7,8,9 supports microcontroller interrupt for external signals. Each has two mask bits to prevent or allow rising or falling edge of its corresponding digital input to trigger second microcontroller interrupt INT2. 11.2.8. Push Button (PBTN) The push button PBTN, when enabled, can be used by the microcontroller to detect a user active-low push button event and to put the system into an ultra-low-power hibernate mode. Once the system is in hibernate mode, PBTN can be used to wake up the system. In addition, PBTN can also be used as a hardware reset for the microcontroller when it is held low for longer than 8s during normal operation. The PBTN input is active low and has a 55kΩ pull-up resistor to 3V. 11.2.9. HP DAC and LP DAC The 8-bit HP DAC can be used as the comparison voltage for the high-speed protection (HP) comparators, or routed for general purpose use via the AB2 signal in the CASM. The HP DAC output full scale voltage is 2.5V. The 10-bit LP DAC can be used as the comparison voltage for the limit protection (LP) comparators, or routed for general purpose use via the AB3 signal in the CASM. The LP DAC output full scale voltage is 2.5V. 11.2.10. ADC Pre-Multiplexer The ADC pre-multiplexer is a 16-to-1 multiplexer that selects between the 3 differential programmable gain amplifier outputs, AB1 through AB9, temperature monitor signal (V TEMP), power monitor signal (V MON), and offset calibration reference (VREF / 2). The ADC pre-multiplexer can be directly controlled or automatically scanned by the auto-sampling sequencer. When the ADC pre-multiplexer is automatically scanned, the unbuffered or sensitive signals should be masked by setting appropriate register bits. 11.2.11. Configurable Analog Signal Matrix (CASM) The CASM has 9 general purpose analog signals labeled AB1 through AB9 that can be used for: Routing the single-ended programmable gain amplifier or analog feed-through output to AB1 through AB9 Routing an analog signal via AB1, AB2, or AB3 to the negative input of a general purpose comparator or phase comparator Routing the 8-bit HP DAC output to AB2 Routing the 10-bit LP DAC output to AB3 Routing analog signals via AB1 through AB12 to the ADC pre-multiplexer Routing phase comparator feed-through signals to AB7, AB8, and AB9, and averaged voltage to AB1 11.2.12.

Functional Description The Application Specific Power Drivers (ASPD, Figure 12-1) module handles power driving for power control applications. PAC5253 has four low-side gate drivers (DRLx), three ultra-high-voltage high-side gate drivers (DXHx). Each gate driver can drive an external MOSFET or IGBT switch in response to high-speed control signals from the microcontroller ports, and a pair of high-side and low-side gate drivers can form a half-bridge driver. The open-drain drivers provide activation control for relays, LEDs, buffers, and other loads. Figure 12-2 below shows typical gate driver connections and Table 20 shows the ASPD resources available on PAC5253. - 37 - Rev 1.10‒August 4, 2015 PAC5253 Power Application Controller Figure 12-2.

Low-Side Gate Driver The DRLx low-side gate driver drives the gate of an external MOSFET or IGBT switch between the low-level V SSP power ground rail and high-level VP supply rail. The DRLx output pin has sink and source output current capability of 1A. Each low-side gate driver is controlled by a microcontroller port signal with 4 configurable levels of propagation delay. 12.3.2. Ultra-High-Voltage Gate Driver The DXHx ultra-high-voltage high-side gate driver drives the gate of an external MOSFET or IGBT switch between its low-level DXSx driver source rail and its high-level DXBx bootstrap rail. The DXSx pin can go up to 600V. The DXHx output pin has 0.5A sink and 0.25A source output current capability. The DXBx bootstrap pin can have a maximum operating voltage of 20V relative to the DXSx pin. The DXSx pin is designed to tolerate momentary switching negative spikes down to -10V without affecting the DXHx output state. Each ultra-high-voltage high-side gate driver is controlled by a microcontroller port signal. For bootstrapped high-side operation, connect an appropriate capacitor between DXBx and DXSx and a properly rated bootstrap diode from VP rail to DXBx. 12.3.3. High-Side Switching Transients Typical high-side switching transients are shown in Figure 12-3(a). To ensure functionality and reliability, the DXSx and DXBx pins must not exceed the peak and undershoot limit values shown. This should be verified by probing the DXSx and DXBx pins directly relative to VSS pin. A small resistor and diode clamp for the DXSx pin can be used to make sure that the pin voltage stays within the negative limit value. In addition, the high-side slew rate dV/dt must be kept within ±50V/ns for DXSx. This can be achieved by adding a resistor-diode pair in series, and an optional capacitor in parallel with the power switch gate. The parallel capacitor also provides a low impedance and close gate shunt against coupling from the switch drain. These optional protection and slew rate control are shown in Figure 12-3(b). - 38 - Rev 1.10‒August 4, 2015 PAC5253 Power Application Controller Figure 12-3.

Power Drivers Control All power drivers are initially disabled from power-on-reset. To enable the power drivers, the microprocessor must first set the driver enable bit to '1'. The gate drivers controlled by the microcontroller ports and PWM signals according to Table 21, with configurable delays as shown in Table 21.

Gate Driver Fault Protection The ASPD incorporates a configurable fault protection mechanism using two protection event signals from the Configurable Analog Front End (CAFE), designated as protection event 1 (PR1) and protection event 2 (PR2) signals. The DRL0/DRL1/DRL2 drivers are designated as low-side group 1, and the DRL3 gate driver are designed as low-side group 2. The DXH0/DXH1/DXH2 ultra-high-voltage gate drivers are designated as high-side group 1. The PR1 signal from the CAFE can be used to disable low-side group 1, high-side group 1, or both depending on the PR1 mask bit settings. The PR2 signal from the CAFE can be used to disable low-side group 2, high-side group 2, or both depending on the PR2 mask bit settings. - 40 - Rev 1.10‒August 4, 2015 PAC5253 Power Application Controller 12.4.

Functional Description 13.2.1. ADC The analog-to-digital converter (ADC) is a 10-bit succesive approximation register (SAR) ADC with 1 μs conversion time and up to 1MSPS capability. The ADC input clock has a user-configurable divider from /1 to /8 of the system clock. The integrated analog multiplexer allows selection from up to 6 direct ADx inputs, and from up to 10 analog inputs signals in the Configurable Analog Front End (CAFE), including up to 3 differential input pairs. The ADC can be configured for repeating or non-repeating conversions and can interrupt the microcontroller when a conversion is finished. 13.2.2. Auto-Sampling Sequencer Two independent and flexible auto-sampling sequencer state machines allow signal sampling using the ADC without interaction from microcontroller core. Each auto-sampling sequencer state machine can be programmed to take and store up to 8 samples each in the ADC result register from different analog inputs, able to control the ADC MUX and ADC Premux as well as the precise timing of the S/H in the Configurable analog front end. The sampling start of the auto-sampling sequencer can be precisely triggered using timers A, B, C, or D or any of their associated PWM edges (high-to-low or lowto-high). It also supports manual start or a ping-pong-scheme, where one auto-sampling sequencer state machine triggers the other when it finishes sampling. The auto-sampling sequencer can interrupt the microcontroller when either conversion sequence is finished. 13.2.3. EMUX Control A dedicated low latency interface controllable by the auto-sampling sequencer or register control allows changing the ADC premultiplexer and asserting/deasserting the S/H circuit in the configurable analog front end, allowing back to back conversions of multiple analog inputs without microcontroller interaction. 13.3.

High-Speed Clock (HCLK) The high-speed clock (HCLK) is derived from the FCLK with a /1, /2, /4 or /8 divider. It supplies the peripheral AHB/APB bus, Timers A to D, dead-time controllers, SPI interface, I 2C interface, UART interface, EMUX interface, SOC bridge interface and memory subsystem, and can go as high as 50MHz. 15.3.4. Auxiliary Clock (ACLK) The auxiliary clock (ACLK) is derived from FCLK with a /1, /2, to /128 divider, and supplies the timer and dead -time blocks. It can be clocked faster or slower than HCLK and can go as high as 100MHz. 15.3.5. Clock Gating The clock tree supports clock gating in deep-sleep mode for the timer block, ADC, SPI interface, I 2C interface, UART interface, memory subsystem and the ARM Cortex-M0 itself. 15.3.6. Ring Oscillator (ROSC) The integrated ring oscillator provides 4 different clocks with 7.5MHz, 9.6MHz, 13.8MHz, and 25.7MHz settings. After reset, the clock tree always defaults to this clock input with the lowest frequency setting. 15.3.7. Trimmed 4MHz RC Oscillator The 1% trimmed 4MHz RC oscillator provides an accurate clock suitable for many applications. It is also used to derive the clock for the Multi-Mode Power Manager. 15.3.8. Internal Slow RC Oscillator An internal 32kHz RC oscillator is used during start up to provide an initial clock to analog circuitry. It is not used as a clock input to the clock tree. 15.3.9. Crystal Oscillator Driver The optional crystal oscillator driver can drive crystals from 2MHz to 10MHz to provide a highly accurate and stable clock into the system. 15.3.10. External Clock Input The clock tree can be supplied with an external clock up to 10MHz. 15.3.11. PLL The integrated PLL input clock is supplied by the FRCLK with an input frequency range of 1MHz to 25MHz. The PLL output frequency is adjustable from 3.5MHz to 100MHz. - 51 - Rev 1.10‒August 4, 2015 PAC5253 Power Application Controller 15.4. Electrical Characteristics Table 27.

Functional Description The ARM Cortex-M0 microcontroller core is configured for little endian operation and includes the fast single-cycle 32-bit multiplier and 24-bit SysTick timer and can operate at a frequency of up to 50MHz. The microcontroller nested vectored interrupt controller (NVIC) supports 25 external interrupts for the device's peripherals and sub-systems. For low-latency interrupt processing, the NVIC also supports interrupt tail-chaining. The wake-up interrupt controller (WIC) is able to wake up the device from low-power modes using any GPIO interrupt, as well as from the RTC or WDT. The ARM Cortex-M0 supports both sleep and deep-sleep low-power modes. The deep-sleep mode supports clock gating to limit standby power even further. Firmware debug support includes 4 break-point and 2 watch-point unit comparators using the serial wire debug (SWD) protocol. The serial wire debug mechanism can be disabled to prevent device access to the firmware in the field. - 53 - Rev 1.10‒August 4, 2015 PAC5253 Power Application Controller 16.4.
