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: 55μA (VCELL=4.4V CON=0V)
   -- Normal: 27μA (VCELL=3.5V CON=0V)
   -- Overdischarge: 2μA (VCELL=1.8V CON=0V)
   -- Overdischarge: 0.1μA 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
