data sheet n pd60308 ips7081(r)(s)pbf intelligent power high side switch features ? over temperature shutdown (with auto-restart) ? short circuit protection (current limit) ? active clamp ? open load detection from power ground ection escription )pbf is a five terminal intelligent power ? logic ground isolated ? esd protection ? ground loss prot ? status feedback d the ips7081(r)(s switch (ips) with built in s hort circuit, over-temperature, esd protection, inductive load capability and diagnostic feedback. the output current is limited at ilim value. current limitation is activate d until the thermal protection acts. the over-temperature pr otection turns off the device if the junction temperatur e exceeds tshutdown. it will automatically restart after the junction has cooled 7c below tshutdown. a diagnostic pin is provided for status feedback of short circuit, ov er-temperature and open load detection. the double level shifter circuitry allows large offsets between the logi c ground and the load. product summary rds(on) 70m ? max. vclamp 70v i limit 5a (typ.) open load 3v package to220 d2pak d-pak IPS7081PBF ips7081spbf ips7081rpbf typical connection out(5) control dg(4) rin vcc(3) load +bat input signal v diag in(2) gnd(1) rdg pull-up resistor for open load off detection 15k +5v www.irf.com 1 downloaded from: http:///
