Overview
The LC05112CMT 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.
A battery protection system can be made by only LC05112CMT and
few external parts..
