called “Overcurrent status of discharge”.

When CS pin voltage excels short circuit detection voltage (VSHORT) and this status lasts longer than short

circuit delay tome （TSHORT）, voltage output of OD pin changes from high level to low level . The discharging control

MOSFET (OD pin) is disabled and discharge is stopped,this status is called “Short Circuit Status”.

Overcurrent status of discharge and short current status are released while the connected impedance between

PB+ and PB- is larger than 450kΩ (typ.). Additionally, when a charger is connected, even the impedance between

PB+ and PB- lowers than 450kΩ (typ.) and CS pin voltage lowers than overcurrent detection voltage of discharge

（

VDIP）, the overcurrent status of discharge or short circuit status will still be released and back to normal operation

mode.

e. Overcurrent of charge status

When CS pin voltage lowers than overcurrent of charge detection voltage (VCIP）and this status lasts longer

than overcurrent of charge delay time（TCIP）during charge process of batteries under normal operation, OC pin

voltage output will change from high level to low level. The charging control MOSFET (OC pin) is disabled and

charge is stopped, his status is called “ Overcurrent of charge Status”.

If CS pin voltage increases higher than overcurrent of charge detection voltage（VCIP） by disconnecting

charger after entering overcurrent of charge status, the overcurrent of charge status will be released and back to

normal operation mode.
