AUIR3317(S)
LOW EMI CURRENT SENSE HIGH SIDE SWITCH
Features
 Load current feedback
 Over current shutdown
 Active clamp
 ESD protection
 Input referenced to Vcc
 Over temperature shutdown
 Switching time optimized for low EMI
 Reverse battery protection
Description
The AUIR3317(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. 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.
