- Detailed Description-Power Management Functions
Battery Detection and Restart of Charging:
In EOC state, If the battery voltage drops below V CHRES and the bit AutoResume is set, the battery detection is
started. The battery switch will be switched into current source mode and V SUPPLY will be regulated to V chlimit (all
charger). The AS3658 measured the battery current with the fuel gauge in this mode. If there is no current, the AS3658
is kept in this state and the bit NoBat is set. Otherwise the bit NoBat is cleared and the charger and the AS3658
continues in battery charging mode. In addition, if the ntc_on<1:0>=01b (NTC temperature supervision is active) the
NoBat bit is cleared and charging is restarted, if a NTC resistor with normal or high temperature is detected.
Overvoltage protection for external linear charger:
During charging with the external linear charger the battery charge controller constantly monitors the voltage of the
charge adapter at pin VCHARGER. In case the charge adapter voltage exceeds V VCHIN,MAX rise for longer than
3mesec and bit ChOVDetEn in the Charger Control register is set to 1, charging is disabled immediately. If the voltage
on the pin VCHARGER drops below V VCHIN,MAX fall , the charger is re-enabled.
