LC05112CMT 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.. 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. 0V battery charging : “Unavailable” Over charge detection voltage : 4.0V to 4.5V (5mV steps) Over charge release hysteresis : 0V to 0.3V (100mV steps) Over discharge detection voltage : 2.2V to 2.8V (50mV steps) Over discharge release hysteresis : 0V to 0.075V (25mV steps) Discharge over current detection : 2.0A to 8.0A (0.5A steps) Charge over current detection : 8.0A to -2.0A (0.5A steps) Over-discharge detection delay time : 20ms or 128ms Typical Applications Smart phone Tablet Wearable device CMOS LSI 1-Cell Lithium-Ion Battery Protection IC with integrated Power MOS FET WDFN6 2.6x4.0, 0.65P, Dual Flag |
