Description

The

AUIPS1041(L)(R)

and

AUIPS1042G

are

three

terminal Intelligent Power Switches (IPS) featuring low

side MOSFETs with over-current, over-temperature, ESD

protection and drain to source active clamp. The

AUIPS1042G is a dual channel device while the

AUIPS1041 is a single channel. These devices offer

protections and the high reliability required in harsh

environments. Each switch provides efficient protection by

turning OFF the power MOSFET when the temperature

exceeds 165°C or when the drain current reaches 4.5A.

The device restarts once the input is cycled. A serial

resistance connected to the input provides the diagnostic.

The avalanche capability is significantly enhanced by the

active

clamp

and

covers

most

inductive

load

demagnetizations.
