Data Sheet No. PD60236 C IPS1021(S)(R)PbF INTELLIGENT POWER LOW SIDE SWITCH Features Product Summary Over temperature shutdown Over current shutdown Rds(on) 25m (max.) Active clamp Vclamp 36V Low current & logic level input ESD protection Ishutdown 35A (typ.) Optimized Turn On/Off for EMI Diagnostic on the input current Packages Description The IPS1021(S)(R)PbF is a three terminal Intelligent 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. The switch provides efficient protection by turning OFF the power MOSFET when the temperature exceeds 165C or when the drain current reaches 35A. The device restarts once the input is cycled. A serial resistance connected to TO-220 DPak D-Pak the input provides the diagnostic. The avalanche capability IPS1021PbF IPS1021SPbF IPS1021RPbF is significantly enhanced by the active clamp and covers most inductive load demagnetizations.
