Description

The IPS1051LPb

Power Switches (IPS) featuring low side MOSFETs with

over-current, over-temperature, ESD protection and drain

to source active clamp. The IPS1052G is a dual channel

device while the IPS1051 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 3A. 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.
