LC05111CMT
1-Cell Lithium-Ion Battery
Protection IC with
Integrated Power MOSFET
Overview
The LC05111CMT is a protection IC for 1−cell lithium−ion
secondary batteries with integrated power MOSFET. 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 LC05111CMT and
few external parts.

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality
should not be assumed, damage may occur and reliability may be affected.
1. Absolute maximum ratings represent the values which cannot be exceeded at any given time.
2. If you intend to use this IC continuously under high temperature, high current, high voltage, or drastic temperature change, even if it used
within the range of absolute maximum ratings or operating conditions, there is a possibility of decrease reliability. Please contact us for
confirmation.
