Battery Protection IC for 1-Cell Lithium-Ion with Integrated Power MOSFET LC05111CMT Overview www.onsemi.com The LC05111CMT is a protection IC for 1cell lithiumion secondary batteries with integrated power MOSFET. Also it integrates highly accurate detection circuits and detection delay circuits to prevent batteries from overcharging, overdischarging, overcurrent discharging and overcurrent charging. A battery protection system can be made by only LC05111CMT and WDFN6 2.6x4.0, 0.65P, few external parts.

Board size 27.4 mm x 3.1 mm x 0.8 mm Junction temperature Tj 125 C 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.
