Battery Installation Detection

The RT5016C also detects TS voltage to monitor the battery status. If PMU is enabled but TS voltage > 90% of VP node

voltage, the RT5016C sets the bit.

NoBAT = 1 an I2C register A10.NoBAT and sets A9.INT bit to

“1”.

No Battery Installed (TS > 90% of VP)

VIN < VUVLO

VUVLO < VIN < VBAT + VOS_L

VBAT + VOS_H < VIN < VOVP

PGOOD

VIN > VOVP

VIN Power Good Status

End_Of_Charge (EOC) Status

The bit EOC in I

2C register A10.EOC can show the EOC status. If EOC = 1, the charger is in EOC state and A9.INT bit

is set to

“1”

Charging Done or Recharging after Termination

Wake-Up Detector

Wake-Up Detector detects VIN or BAT plug-in events. Once BAT plugs in or VIN plugs in for a 19ms deglitch time, the

WAKE pin will provide a 90ms width high pulse. The timing diagram is shown as below :
