® RT5016C I2C Programmable Multi-Channel PMU with Battery Charger for CMOS DSC/DV General Description The RT5016C is a complete power supply solution for digital still cameras and other hand held devices. The RT5016C is composed of a multi-channel DC/DC power converter unit, a single-cell linear Li-ion battery charger, a charger type detector, and an I2C control interface. The power converter unit includes one synchronous stepup converter (CH1), one synchronous step-up/down converter (CH2), three synchronous step-down converters (CH3/4/5), two LDOs with input power as low as 1.5V (CH6/8), one WLED driver in synchronous high-voltage step-up mode or low-voltage current regulator mode (CH7), and a keep-alive LDO (CH9) for RTC application. All converters are internally frequency compensated and integrate power MOSFETs. The power converter unit provides complete protection functions : over-current, thermal shutdown, over-voltage, and under-voltage protection. The RT5016C has a WAKEUP impulse generation circuitry to monitor VIN or BAT installation event. To fulfill most of applications, the RT5016C has six preset power-on/off sequences. The battery charger includes Auto Power Path Management (APPM). No external MOSFETs are required. The charger can enter sleep mode when power is removed. Charging tasks are optimized by using a control algorithm to vary the charge rate, including pre-charge mode, fast charge mode and constant voltage mode. The charge current can also be programmed via the I2C control interface. The battery regulation voltage and current can be adjusted by JEITA standard temperature control or other schemes set via the I2C interface. The internal thermal feedback circuitry regulates the die temperature to optimize the charge rate for all ambient temperatures. The charging task will always be terminated in constant-voltage mode when the charging current reduces to the termination current of 10% x ICHG_FAST. The charger includes undervoltage and over-voltage protection for the supply input voltage, VIN. The charger includes USB charger detection circuitry via D+ and D- pins of USB interface to detect USB standard downstream ports (SDP), USB charging downstream port (CDP), dedicated charger port (DCP), or Apple/Sony charger ports. RT5016C uses some indicators to show charger states : two open drain ports CHG and CHG2, and an interrupt (INT) to immediately notify the state change. The RT5016C has I2C interface to control rich functions of Power Converter Unit and Charger Unit, and is available in the WQFN-40L 5x5 package.

DS5016C-01 December 2014 RT5016C Operation The RT5016C is an integrated power solution for digital still cameras and other small handheld devices. It includes six DC/DC converters, a WLED driver, a RTC LDO, and a fully integrated single-cell Li-ion battery charger. CH1 : Step-Up DC/DC Converter CH1 is a step-up converter for motor driver power. The converter operates at PFM or PWM current mode which can be set by I2C interface. CH8 : Generic LDO CH8 is a generic low voltage LDO for multiple purpose power. CH9 : Keep Alive LDO and RTC CH9 is a LDO providing a 3.05V output for real time clock. Charger Unit A Li-ion battery charger with automatic power path management is designed to operate in below modes. CH2 : Step-Up/Down DC/DC Converter CH2 is a step-up/down converter for I/O power. The converter operates at PFM or PWM current mode which can be set by I2C interface. Pre-Charge Mode When the output voltage is lower than 2.8V, the charging current will be reduced to a ratio of fast-charge current set by A8.ISETA [3:0] to protect the battery life-time. CH3 : Step-Down DC/DC Converter CH3 is a step-down converter for core power. The converter operates at PFM or PWM current mode which can be set by I2C interface. Fast-Charge Mode When the output voltage is higher than 3V, the charging current will be equal to the fast-charge current set by A8.ISETA [3:0]. CH4 : Step-Down DC/DC Converter CH4 is a step-down converter for memory power. The converter operates at PFM or PWM current mode which can be set by I2C interface. CH5 : Step-Down DC/DC Converter CH5 is a step-down converter. The converter operates at PFM/PWM current mode. CH6 : Generic LDO CH6 is a generic low voltage LDO for multiple purpose power. Constant Voltage Mode When the output voltage is near 4.2V and the charging current falls below the termination current for a deglitch time of 25ms, the charger will be turned off and CHG will go to high. Re-Charge Mode When the chip is in charge termination mode, the charging current gradually goes down to zero. Once the battery voltage drops to below 4.1V for 100ms, the charger will resume charging operation. CH7 : WLED Driver CH7 is a WLED driver that can operate in either current source mode or synchronous step-up mode which is determined by I2C interface control signal.

The operation mode is determined by setting I2C. The P-MOSFET in step-up mode can be controlled to disconnect the output loading. When CH7 works in current source mode, it likes a LDO and regulates the current by FB7 voltage. The LED current is defined by the FB7 voltage as well as the external resistor between FB7 and GND. The FB7 regulation voltage can be set in 31 steps from 8mV to 250mV. If CH7 works in synchronous step-up mode, it can support an output voltage up to 15V or 21V controlled by I2C interface. The LED current is also set via an external resistor and FB7 regulation voltage. The WLED current can be set by the following equation : ILED (mA) = [250mV / R (Ω)] x EN7_DIM7 [4:0] / 31 where R is the current sense resistor from FB7 to GND and for the EN7_DIM7 [4:0] / 31 ratio, refer to the I2C control register file.

The RT5016C provides a 3.05V output LDO for real-time clock. The LDO features low quiescent current (3μA), reverse leakage prevention from output node and high output voltage accuracy. This LDO is always on, even when the system is shut down. For better stability, it is recommended to connect a 0.1μF capacitor to the RTCPWR pin. The RTC LDO includes pass transistor body diode control to avoid the RTCPWR node from back-charging into the input node VDDI. Switching Frequency The converters of CH1, CH3, CH4 and CH5 operate in PWM mode with 2MHz switching frequency. The converters of CH2 and CH7 operates in PWM mode with 1MHz switching frequency.

The RT5016C includes UVLO circuits to monitor VDDI and SYS voltage status. SYS PVD1 VDDI = Max (SYS, PVD1) Charger Unit The RT5016C includes a Li-ion battery charger with Automatic Power Path Management. The charger is designed to operate in below modes : Pre-Charge Mode When the output voltage is lower than 2.8V, the charging current will be reduced to a ratio of the fast-charge current set by A8.ISETA [3:0] to protect the battery life-time. The timing diagram is showed in Figure 3. Fast-Charge Mode When the output voltage is higher than 3V, the charging current will be equal to the fast-charge current set by A8.ISETA [3:0] shown as Figure 3. Constant Voltage Mode When the output voltage is near 4.2V and the charging current falls below the termination current for a deglitch time of 25ms, the charger will be disabled and CHG will go high. The timing diagram is showed in Figure 3. Re-Charge Mode When the chip is in charge termination mode, the charging current gradually goes down to zero. Once the battery voltage drops to below 4.1V for a deglitch time of 100ms, the charger will resume charging shown as Figure 3. 4.16 to 4.2 to 4.23V −40°C to 85°C Battery Voltage Charging Current VRECH If VPRECH ISETL = 1, ISETU = 1 ISETL = 0, ISETU = X ITERMI = 10% x ICHG_FAST If ISETL = 0, ISETU = 0 ITERMI = 3.3% x ICHG_FAST ICHG_PRE = 10% x ICHG_FAST ITERM2 Time Figure 3 Copyright © 2014 Richtek Technology Corporation.

For example, the system load current may have activated the APPM loop which reduces the available charging current or the device has entered thermal regulation because the IC junction temperature has exceeded TREG. However, once the duration exceeds the fault-time, the CHG output pin will flash at approximately 4Hz to indicate a fault condition and the charge current will be reduced to about 1mA. There are four methods to release the Fault-time : Re-plug power Toggle EN Enter/exit suspend mode Remove Battery OVP The fault-time is inverse proportional to the charger current. 1 Fault-Time Icharge Example : If the sensing battery temperature is hot or cold, the charge current will reduce to half charge current. So, the fault-time will increase to be double. JEITA Battery Temperature Standard CV regulation voltage will be changed in the following battery temperature ranges : 0°C to 10°C and 45°C to 60°C. This function can be disabled by A9.VSETH and A9.VSETC. CC regulation current will be changed in the following battery temperature ranges : 0°C to 10°C and 45°C to 60°C.

Charging is suspended when the voltage at the TS pin is out of normal operating range. The internal timer is then paused, but the value is maintained. When the TS pin voltage returns to normal operating range, charging will resume and the safe charge timer will continue to count down from the point where it was suspended. Note that although charging is suspended due to the battery pack temperature fault, the CHG pin will flash at 0.5Hz and indicate charging. The 3.3V at the VP pin is buffered by the RT5016C once it is in charging state or its PMU part is enabled. If a 100kΩ NTC thermal resistor is used, the A0.TSSEL bit should be set to “1”. If a 10kΩ NTC thermal resistor is used, the A0.TSSEL bit should be set to “0”. The TSSEL bit determines the TS threshold levels for 0°C and 60°C. It also defines the TS threshold levels used in JEITA operation. The choosing method of R1 and R2 to meet battery temperature monitoring shows as below. Case 1 : TSSEL = H (For 100kΩ NTC) : Case 2 : TSSEL = L (For 10kΩ NTC) : VP VP VP VP R1 TS 0.74 x VP + - R2 0.28 x VP + 0.6 x VP R1 Too Cold TS + - R2 Too Hot - + Too Cold Too Hot 0.28 x VP RNTC RNTC Figure 4 Figure 5 Too Cold Temperature Too Cold Temperature RCOLD = RNTC RCOLD = RNTC Too Hot Temperature Too Hot Temperature RHOT = RNTC RHOT = RNTC R2 RCOLD = 0.74 --------------------------------------- (1) RCOLD R1 R2 R2 + RCOLD = 0.6 ------------------------------------------ (1) RCOLD +R1+R2 R2 RHOT = 0.28 ----------------------------------------- (2) RHOT R1 R2 R2 + RHOT = 0.28 ------------------------------------------ (2) RHOT +R1+R2 Form (1), (2) Form (1), (2) R1 = RCOLD RHOT 2.457 R1 = 0.9 RCOLD RHOT R2 = 0.389 R1 RHOT R2 = 0.388 R1 RHOT If R2 < 0 If R2 < 0 RCOLD = 0.74 ---------------------------------------------- (3) RCOLD R1 RCOLD = 0.6 ------------------------------------------------- (3) RCOLD +R1 Form (3) R R1 = COLD RCOLD 0.74 Copyright © 2014 Richtek Technology Corporation.

DS5016C-01 December 2014 RT5016C The Control Temperature Used in JEITA Operation The above calculation gives R1 and R2. JEITA control thresholds for full charging current and 4.2V regulation voltage are at TS/VP ratio = 32% and 52% (for TSSEL = L), 35% and 64% (for TSSEL = H). With the ratio, the corresponding NTC thermistor resistances from the resistors in the voltage divider circuit can be obtained. According to the NTC resistances, the corresponding temperatures can be found. The two temperatures are the control temperatures used in JEITA operation. Operation State Diagram for TS Pin (TSSEL = H) Any State No 74% x VVP < VTS < 2.85V No VTS > 2.85V Or VTS < 28% x VVP Yes Yes TS fault State Battery Remove State ICHG = 0A ICHG = 0A CHG 4Hz flash rate CHG 4Hz flash rate Power Switch For the charger, there are three power scenarios : When a battery and an external power supply (USB or adapter) are connected simultaneously If the system required load exceeds the input current limit, the battery will be used to supplement the current to the load. However, if the system load is less than the input current limit, the excess power from the external power supply will be used to charge the battery. When only the battery is connected to the system The battery provides the power to the system. When only an external power supply is connected to the system The external power supply provides the power to the system. Input DPM Mode For the charger, the input voltage is monitored when USB100 or USB500 is selected. If the input voltage is lower than VDPM, the input current limit will be reduced to stop the input voltage from dropping further. This can prevent the IC from damaging improperly configured or inadequately designed USB sources. If VIN charger type is detected as SDP, the DPM function always is enabled. For other types, the DPM function always is disabled but user can set A0.ENDPM to turn on the DPM function. Enable the charger VIN DPM function. But if VIN charger type is detected as SDP (CHG_TYP [2:0] = 000), the DPM function always is enabled. ENDPM 0 : VIN DPM function disabled. 1 : VIN DPM function enabled.

When the SYS pin voltage is reduced to VAPPM, the RT5016C will automatically operate in APPM mode. In this mode, the charging current is reduced while the SYS current is increased to maintain system output. In APPM mode, the battery termination function is disabled.

When the SYS voltage decreases below the battery voltage, the battery will kick in to supplement the system load until the SYS voltage rises above the battery voltage. While in supplement mode, there is no battery supplement current regulation. However, a built-in short-circuit protection feature is available to prevent any abnormal current situation. While the battery is supplementing the load, if the difference between the battery and SYS voltage exceeds the short-circuit threshold voltage, SYS will be disabled. After a shortcircuit recovery time, tSHORT_R, the counter will be restarted. In supplement mode, the battery termination function is disabled. Note that the battery supply mode exiting condition is VBAT − VSYS < 0V. Thermal Regulation and Thermal Shutdown The charger provides a thermal regulation loop function to monitor the device temperature. If the die temperature rises above the regulation temperature, TREG, the charge current will automatically be reduced to lower the die temperature. However, in certain circumstances (such as high VIN, heavy system load, etc) even with the thermal loop in place, the die temperature may still continue to increase. In this case, if the temperature rises above the thermal shutdown threshold, TSD, the internal switch between VIN and SYS will be turned off. The switch between the battery and SYS will remain on however, to allow continuous battery power to the load. Once the die temperature decreases by ΔTSD, the internal switch between VIN and SYS will be turned on again and the device returns to normal thermal regulation. The internal thermal feedback circuitry regulates the die temperature to optimize the charge rate for all ambient temperatures. Copyright © 2014 Richtek Technology Corporation. All rights reserved.

The maximum power dissipation depends on the thermal resistance of the IC package, PCB layout, rate of surrounding airflow, and difference between junction and ambient temperature. The maximum power dissipation can be calculated by the following formula : For the best performance of the RT5016C, the following PCB layout guidelines must be strictly followed. Place the input and output capacitors as close as possible to the input and output pins respectively for good filtering. Keep the main power traces as wide and short as possible. The switching node area connected to LX and inductor should be minimized for lower EMI. For recommended operating condition specifications, the maximum junction temperature is 125°C. The junction to ambient thermal resistance, θJA, is layout dependent. For WQFN-40L 5x5 package, the thermal resistance, θJA, is Place the feedback components as close as possible to the FB pin and keep these components away from the noisy devices. 27.5°C/W on a standard JEDEC 51-7 four-layer thermal test board. The maximum power dissipation at TA = 25°C can be calculated by the following formula : Connect the GND and Exposed Pad to a strong ground plane for maximum thermal dissipation and noise protection. To make CH1 and whole chip stable, the power path from the PVD1 pin to its output capacitors must be as short (≤ 1mm is better) and wide as possible. To make CH4 and CH5 stable, the power path from the PVD45 pin to its input capacitors must be as short (≤ 1mm is better) and wide as possible. PD(MAX) = (TJ(MAX) − TA) / θJA where TJ(MAX) is the maximum junction temperature, TA is the ambient temperature, and θJA is the junction to ambient thermal resistance. PD(MAX) = (125°C − 25°C) / (27.5°C/W) = 3.63W for WQFN-40L 5x5 package Maximum Power Dissipation (W)1 The maximum power dissipation depends on the operating ambient temperature for fixed T J(MAX) and thermal resistance, θJA. The derating curve in Figure 6 allows the designer to see the effect of rising ambient temperature on the maximum power dissipation. 4.0 Four-Layer PCB 3.2 2.4 1.6 0.8 0.0 0 25 50 75 100 125 Ambient Temperature (°C) Figure 6.
