IPS521

Data Sheet No.PD 60158-H IPS521/IPS521S FULLY PROTECTED HIGH SIDE POWER MOSFET SWITCH Features Over temperature protection (with auto-restart) Short-circuit protection (current limit) Active clamp E.S.D protection Status feedback Open load detection Logic ground isolated from power ground Product Summary Rds(on) V clamp I Limit V open load 80mΩ (max) 50V 10A 3V Description The IPS521/IPS521S are fully protected five terminal high side switches with built in short-circuit , overtemperature, ESD protection, inductive load capability and diagnostic feedback. The output current is controlled when it reaches I lim value. The current limitation is activated until the thermal protection acts. The over-temperature protection turns off the high side switch if the junction temperature exceeds Tshutdown. It will automatically restart after the junction has cooled 7 oC 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 ground. Truth Table Op.
