On-Semi - LC05711ARA: Battery Protection IC
The LC05711ARA is a protection IC for 1-cell lithium-ion secondary batteries with integrated power MOSFET. 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
• 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 ±0.70A
Discharge over-current detection ±0.70A
• Discharge/Charge over-current detection is compensated for temperature dependency of power FET
• ECP30 WLP package
