11.5.Charge Overcurrent Status
When CS pin voltage lowers than charge overcurrent detection voltage (VCIP) and this status lasts
longer than charge overcurrent delay time (TCIP) during charge process of batteries under normal
operation, OC pin voltage output will change from high potential to low potential. At this time,
MOSFET (OC pin) is disabled and charge stopped. This status is called “Charge Overcurrent
Status”.
If CS pin voltage increases higher than charge overcurrent detection voltage (VCIP) by disconnecting
charger after enter charge overcurrent status, the charge overcurrent status will be released and
restore to normal operation mode.
