SA45141

SA45141 THREE OR FOUR-CELL LI+ BATTERY PROTECTION CIRCUIT 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 SSOP-20-225-0.65 * 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: two types(2.3±0.1V, 2.9±0.1V ) * Overdischarge release voltage: 3.0±0.15V * Overcurrent detection voltage: two types(150±15mV,200±15mV) APPLIC...
