CM1401-GT Integrated Circuit by ICM | TSSOP-16 Package

CM1401-GT | 4-String Lithium/Iron Battery Protection IC
Package: TSSOP-16 | Pins: 16 | Type: SMD

The CM1401-GT belongs to the CM1041 series, a high-precision protection IC designed for 4-string lithium-ion and lithium-iron (LiFePO₄) battery packs. It integrates voltage detection, current sensing, and temperature monitoring circuits to ensure comprehensive protection and reliable operation.

By monitoring each cell’s voltage, charge/discharge current, and pack temperature, the CM1401-GT provides overcharge, over-discharge, over-current (charge/discharge), short-circuit, and thermal protections. Protection delays for overcharge, over-discharge, and over-current conditions are externally adjustable via capacitors, offering design flexibility.
