LC05112CMT
CMOS LSI
1-Cell Lithium-Ion Battery
Protection IC with integrated
Power MOS FET
http://onsemi.com
Overview
The LC05112CMT is a protection IC for 1-cell lithium-ion secondary
batteries with integrated power MOS FET. Also it integrates highly
accurate detection circuits and detection delay circuits to prevent batteries
from over-charging, over-discharging, over-current discharging and
over-current charging.
A battery protection system can be made by only LC05112CMT and
few external parts..
WDFN6 2.6x4.0, 0.65P, Dual Flag
Feature
Charge-and-discharge power MOSFET are integrated at Ta = 25C, VCC = 4.5V
ON resistance (total of charge and discharge) 11.2m (typ)
Highly accurate detection voltage/current at Ta = 25C, VCC = 3.7V
Over-charge detection
±25mV
Over-discharge detection
±50mV
Charge over-current detection
±0.7A
Discharge over-current detection ±0.7A
Delay time for detection and release (fixed internally)
Discharge/Charge over-current detection is compensated for temperature dependency of power FET.
