Description

The IPS1021(S)(R Power 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. T he switch provides efficient pr otection by turning OF F the power MOSFET when the temperature exceeds 165°C or when the drain current reaches 35A. T he 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.
