Description
The IR3313PbF is a fully protected 4 terminals high side switch. The input signal is referenced to Vcc. When the input
voltage Vcc - Vin is higher than the specified threshold, the output power
Mosfet is turned on. When the Vcc - Vin is lower than the specified Vil threshold, the output
Mosfet is turned off. A current proportional to the power
Mosfet current is sourced to the Ifb pin. Over current shutdown occurs when Vst-Vin > 4.5V. The current shutdown threshold is adjusted by selecting the proper RIfb. Either over current and over temperature latches off the switch. The device is reset by pulling the input pin high. Other integrated protections (ESD, reverse battery, active clamp) make the switch very rugged in automotive environment.
