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.
