Data Sheet No.PD 6155 IPS511/IPS511S FUY PROTECTED IG SIDE POWER MOSFET SWITC Features Over temperature protection (with auto-restart) Short-circuit protection (current limit ) Active clamp E.S.D protection Status feedback Open load detection ogic ground isolated from power ground Product Summary R ds(on) 135mΩ (max) V clamp 5V I imit 5A V open load 3V Description The IPS511/IPS511S are fully protected five terminal high side switches 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. Truth Table Op.
