| Data Sheet No. PD60237_B IPS1031(S)(R) INTELLIGENT POWER LOW SIDE SWITCH Features * * * * * * * Over temperature shutdown Over current shutdown Active clamp Low current & logic level input ESD protection Optimized Turn On/Off for EMI Diagnostic on the input current Product Summary Rds(on) 50m (max.) Vclamp 36V Ishutdown 18A (typ.) Packages Description The IPS1031(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 165C or when the drain current reaches 18A. 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.
