ONE CELL LITHIUM-ION/POLYMER BATTERY PROTECTION IC

DESCRIPTION

FEATURES



High-accuracy voltage detection circuit

 Overcharge detection voltage

4.200 to 4.400V; Accuracy: ±50mV

 Overcharge release voltage

This protection IC was developed for use with

lithium-ion/lithium polymer 1-cell serial batteries.

It detects overcharge, overdischarge, discharge

overcurrent and other abnormalities, and functions to

protect the battery by turning off the external

MOSFET.

3.900 to 4.400V; Accuracy: ±50mV

 Overdischarge detection voltage

2.30 to 3.00V; Accuracy: ±100mV

 Overdischarge release voltage

2.30 to 3.40V; Accuracy: ±100mV

 Discharge overcurrent detection voltage

150mV; Accuracy: ±100mV

The IC also has a built-in timer circuit (for detection

delay times), so fewer external parts can be used in

protection circuit configuration.

 Short-circuiting detection voltage

1.35V; Accuracy: ±100mV



Delay times are generated by an internal circuit

(external capacitors are unnecessary).

 Overcharge delay time:100ms typ.

 Overdischarge delay time: 50ms typ.

 Discharge overcurrent delay time:10ms typ.

 Charge overcurrent detection voltage:10ms typ.

 Short circuit delay time: 5μs typ.

Power-down function ꢀYesꢁ / ꢀNoꢁ are selectable

(See Model List).

Auto overdischarge recovery function ꢀYesꢁ /

ꢀNoꢁ are selectable (See Model List).

Low current consumption

 Operation mode: 3.0μA typ. 6.0μA max.

(V_CC=3.9V)

The A4001 is available in SOT-26 package.
