LC05732ARA
Battery Protection IC,
Integrated Power MOSFET,
1-Cell Lithium-Ion Battery
Overview
The LC05732ARA 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.
In addition, main system can execute the power-on reset of itself by turning off
the charge FET and discharge FET of LC05732ARA for a certain time period,
with a reset signal.
A battery protection system can be made by only LC05732ARA 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 ) 4.8m (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
: “Inhibit”
• Auto wake-up function battery charging
: “Inhibit”
• Forcible charge-FET and discharge-FET OFF mode
RSTB>VDD*0.9: Charge-FET and Discharge-FET=ON
RSTB<VDD*0.1: Charge-FET and Discharge-FET=OFF
Typical Applications
• Smart phone
• Tablet
• Wearable device
