THREE OR FOUR-CELL LI+ BATTERY PROTECTION CIRCUIT

SSOP-20-225-0.65

DESCRIPTION

The SA45141 is a three- or four-cell Lithium-Ion Batteries protection

circuit. SA45141 protects for Lithium-Ion Batteries. It has functions

below: Overcharge detection, Overdischarge detection, Overcurrent

detection. When the Lithium-Ion Batteries is in state of overcharge,

overdischarge and overcurrent. The IC turns off and on the external

MOSFET to protect the batteries.

FEATURES

* Low current consumption

-- Overcharge: 55

μA (VCELL=4.4V CON=0V)

-- Normal: 27

μA (VCELL=3.5V CON=0V)

-- Overdischarge: 2

μA (VCELL=1.8V CON=0V)

-- Overdischarge: 0.1

μA Max(VCELL=1.0V CON=0V)

* Overcharge detection voltage:

two types (4.350±0.025V, 4.250±0.025V)

*Overcharge detection hysteresis voltage:

two types (200±60mV, 8±8mV)

* Overdischarge detection voltage: three types(2.3±0.1V, 2.6±0.2V ,

2.9±0.1V)

* Overdischarge release voltage:

two types (3.0±0.15V, 3.0±0.20V)

* Overcurrent detection voltage: two types(150±15mV,200±15mV)

APPLICATIONS

* 3-cell or 4-cell lithium-ion batteries

* Notebook PC

* Electric bicycle

* Electric tools
