LC05132C01MT

Overview

The LC05132C01MT 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 LC05132C01MT for a certain

time period, with a reset signal.

A battery protection system can be made by only LC05132C01MT and few

external parts.
