Description

The AUIR3314(S) 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 Vifb-Vin > 4.7V. 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.
