MM1414 Overview
Pin name I/O Overcharge detection output pin 1 OV Output NPNTr open collector output Normal: high impedance Overcharge: Low 2 N.C Not connected Overcurrent detection pin Monitors load current equivalently by the voltage drop between discharge control 3 CS Input FET source and drain, and makes DCHG pin high when the voltage goes below overcurrent detection voltage, turning off discharge control FET.
