Description

The IPS1021(S)(R

Switch (IPS) that features a low side MOSFET with over-

current, over-temperature, ESD protection and drain to

source active clamp. This device offers protections and

the high reliability required in harsh environments. The

switch provides efficient protection by turning OFF the

power MOSFET when the temperature exceeds 165°C or

when the drain current reaches 35A. 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.
