LC05112CMT

LC05112CMT CMOS LSI 1-Cell Lithium-Ion Battery Protection IC with integrated Power MOS FET http://onsemi.com 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..
