Suspend Mode
When USUS = 1, the charger will enter Suspend Mode. In Suspend Mode, the CHG pin is high impedance and
IUSUS(MAX) < 300
μA.
Charging Current Decision
The charge current can be set according to the I2C register A8.ISETA [3:0] setting :
VIN

BAT > 3.1V
VIN > 3.75V when BAT >3.1V

detection after VIN plug in
and larger than threshold.
