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.
