26 / 63 page  ADP5350 Data Sheet Rev. B | Page 26 of 63 BATTERY CHARGER OPERATIONAL FLOWCHART Figure 43. ADP5350 Charger Operational Flowchart BATTERY VOLTAGE-BASED FUEL GAUGE Overview The ADP5350 Li-Ion battery fuel gauge is based on the voltage measurement with a 12-bit ADC. SOC is calculated with a battery model integrated in the ADP5350. Ten voltage values based on the battery characterization and the battery internal resistance at different temperatures must be written to the V_SOC_x register and RBAT_x register of the ADP5350 for SOC calculation. Operation Mode The ADP5350 fuel gauge, in shut down mode by default, provides extremely low standby current consumption from the battery. After the fuel gauge function is enabled, two operation modes can be selected: active mode and sleep mode. The fuel gauge operation mode is controlled by the I2C. In active mode, the battery SOC is updated every 1 sec by the sensed battery voltage, which achieves better accuracy and indicates the remaining battery capacity but consumes 160 μA VBUSOK YES NO FAST CHARGE YES WATCHDOG EXPIRED START tSAFE ILIM = 100mA TIME FAULT/ BAD BATTERY RUN BATTERY DETECTION IBUSLIM = HIGH IVIN = ILIM THERMLIM = HIGH TEMP = TLIM WATCHDOG EXPIRED START tSAFE ILIM = 100mA TIME FAULT/ BAD BATTERY (SEE SAFETY TIMER SECTION) CC MODE CHARGING CV MODE CHARGING NO NO CHARGE COMPLETE YES YES NO NO TRICKLE CHARGE YES YES NO NO YES NO NO YES NO NO YES VBUS OK VBUS OK YES YES NO NO NO YES YES NO YES YES NO YES POWER-ON RESET RESET ALL REGISTERS RUN BATTERY DETECTION tSTART EXPIRED tWD EXPIRED tWD EXPIRED tSAFE/tTRK EXPIRED tSAFE/tCHG EXPIRED VBSNS = VTRM VBSNS ≤ 3.5V VBSNS ≤ VRCH IOUT < IEND POWER DOWN VBSNS < VTRK VBSNS < VTRK IVIN < ILIM TEMP < TLIM |
