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.

(4) Input thresholds are measured directly between the input pin and the tab. Any parasitic resistance in common between
the load current path and the input signal path can significantly affect the thresholds.
(5) Rdson is measured between the tab and the Out pin, 5mm away from the package.
