D scription

The IR3314(S)PbF

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.
