Description

The IR 3312(S) is a Fully Protected 4 terminal high side switch.

The input signal is referenced to Vcc. When the input voltage

Vcc - Vin is higher than the specified Vih threshold, the output

power MOSFET is turned-on. When Vcc - Vin is lower than

the specified Vil threshold, the output MOSFET is turned-off.

A sense current proportional to the current in the power Mosfet

is sourced to the Ifb pin. Over-current shutdown occurs when

Vifb - Vin > 4.5 V. The current shutdown threshold is adjusted

by selecting the proper RIfb. Either over-current and over-tem-

perature latches off the switch. The device is reset by pulling

the input pin high. Other integrated protections ( ESD, reverse

battery, active clamp ) make the IR3312(S) very rugged and

suitable for the automotive environment.
