Description
The IR3313(S)PbF is a fully protected 4 terminals high Packages
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 ViI threshold, the
output Mosfet is turned off. A current proportional to the
power Mosfet current is sourced to the lfb pin. Over
current shutdown occurs when Vst-Vin > 4.5V. The current TO-220 szak
shutdown threshold is adjusted by selecting the proper IR3313 Pin 1tl2"'d
leb. 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.
