SA45141 Datasheet, PDF (1/9 Pages) Silan Microelectronics Joint-stock – THREE OR FOUR-CELL LI+ BATTERY PROTECTION CIRCUIT

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: three types(2.3±0.1V, 2.6±0.2V ,
2.9±0.1V)
