Description
The AUIR3316(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.
