Data sheet N PD60308 IPS7081(R)(S)PbF INTELLIGENT POWER HIGH SIDE SWITCH Features Product Summary Over temperature shutdown (with auto-restart) Short circuit protection (current limit) Rds(on) 70m max. Active clamp Vclamp 70V Open load detection Logic ground isolated from power ground I Limit 5A (typ.) ESD protection Open load 3V Ground loss protection Status feedback Package Description The IPS7081(R)(S)PbF is a five terminal Intelligent Power Switch (IPS) with built in short circuit, over-temperature, ESD protection, inductive load capability and diagnostic feedback. The output current is limited at Ilim value. Current limitation is activated until the thermal protection acts. The over-temperature protection turns off the device if the junction temperature exceeds Tshutdown. It will TO220 DPak D-Pak automatically restart after the junction has cooled 7C IPS7081PbF IPS7081SPbF IPS7081RPbF below Tshutdown. A diagnostic pin is provided for status feedback of short circuit, over-temperature and open load detection. The double level shifter circuitry allows large offsets between the logic ground and the load.
