The LC05132C01NMT 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 LC05132C01NMT for a certain time period, with a reset signal. A battery protection system can be made by only LC05132C01NMT and few external parts.
