Preliminary Data Sheet No.PD 60158-G 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 Description The IPS521/IPS521S are fully protected five terminal high side switch with built in short-circuit, over-temperature, ESD protection, inductive load capability and diagnostic feedback. The output current is controlled when it reaches Ilim 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 o C 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.
