Vclamp 36V Ishutdown 35A (typ.) Packages Description The IPS1021(S)(R) is a three terminal Intelligent Power Switch (IPS) that features a low side MOSFET with overcurrent, 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.
