ONE CELL LITHIUM-ION/POLYMER BATTERY PROTECTION IC

(2) When CS pin voltage is equal to or higher than the charge overcurrent detection voltage (VCIP) by

charging and the V_CCpin voltage is higher than the overdischarge release voltage (VODR).

Products with Auto Overdischarge Recovery Function

When the battery voltage falls below than the overdischarge detection voltage (VODP) during discharging in

the normal status and the detection continues longer than the overdischarge detection delay time (TOD), the

A4001 series will turn the discharging control MOSFET off(OD pin) so as to stop discharging. This condition is

called the overdischarge status.

The overdischarge status will be released by three cases:

(1) When CS pin voltage is equal to or lower than the charge overcurrent detection voltage (VCIP) by

charging and the V_CCpin voltage is higher than the overdischarge detection voltage (VODP).

(2) When CS pin voltage is equal to or higher than the charge overcurrent detection voltage (VCIP) by

charging and the V_CCpin voltage is higher than the overdischarge release voltage (VODR).

(3) Without connecting a charger, if the V_CCpin voltage is higher than overdischarge release voltage (VODR),

the overdischarge status will be released, namely Auto Overdischarge Recovery Function.

Charge Overcurrent Status

When a battery is in the normalstatus, the voltage of the CS pin is lower than the charge overcurrent detection

voltage (VCIP). When the charge current is higher than the specified value and the status lasts beyond the

charge overcurrent detection delay time(TCIP), the charge control MOSFET will be turned off and charging is

stopped. This status is called the charge overcurrent status.

This IC will be restored to the normal status from the charge overcurrent status when the voltage at the CS pin

returns to charge overcurrent detection voltage (VCIP) or higher by removing the charger.

0V Battery Charging Function ꢀAvailableꢁ

This function is used to recharge a connected battery which voltage is 0V due to self-discharge. When the 0V

battery charge starting charger voltage (V0V) or a higher voltage is applied between the battery+ (BATT+)

and battery- (BATT-) pins by connecting a charger, the charging control MOSFET gate is fixed to the V_CCpin

voltage.

When the voltage between the gate and the source of the charging control MOSFET becomes equal to or

higher than the turn on voltage due to the charger voltage, the charging control MOSFET is turned on to

initiate charging. At this time, the discharging control MOSFET is off and the charging current flows through

the internal parasitic diode

In the discharging control MOSFET. When the battery voltage becomes equal to or higher than overdischarge

detection voltage (VODP), the A4001 series will enter into the normal status.
