LC05711ARA Battery Protection IC, Integrated Power MOSFET, 1-Cell Lithium-Ion Battery
●Overview
■The LC05711ARA 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 LC05711ARA and few external parts.
●Features
■Charge-and-discharge power MOSFET are integrated at Ta = 25°C,VCC = 4.0V
■ON resistance (total of charge and discharge ) 4.8mΩ (typ)
■Highly accurate detection voltage/current at Ta = 25°C, 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 : “Permission”
■Auto wake-up function battery charging :“Permission”
