1 / 9 page 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 ORDERING INFORMATION Device Package Overcharge detect voltage ( V) Overcharge detect hysteresis voltage ( mV) Overdis- charge detect voltage ( V) Overdis- charge release voltage ( V) Overcurrent detect voltage ( mV) SA45141SC 4.350±0.025 200±60 2.3±0.1 3.00±0.15 150±15 SA45141SD 4.350±0.025 200±60 2.6±0.2 3.00±0.20 150±15 SA45141SE 4.350±0.025 200±60 2.9±0.1 3.00±0.15 200±15 SA45141SH SSOP-20-225-0.65 4.250±0.025 8±8 2.9±0.1 3.00±0.15 200±15 HANGZHOU SILAN MICROELECTRONICS CO.,LTD REV:1.5 2009.06.05 Http: //www.silan.com.cn Page 1 of 10 |
