LC05112CMT - 1-Cell Lithium-Ion Battery Protection IC

Description

R2 1k 2k  C1 2.2 4.7u F

We don’t guarantee the characteristics of the circuit shown above.

TST pin would be better to be connected to VSS pin, though it is connected to VSS with internal resistor (100k typ).

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.. WDFN6 2.6x4.0, 0.65P, Dual Flag Feature  Charge-and-discharge power MOSFET are integrated at Ta = 25C, VCC = 4.5V ON resistance (total of charge and discharge) 11.2m (typ)  Highly accurate detection voltage/current at Ta = 25C, VCC = 3.
