Data Sheet No.PD60156-K IPS511G/IPS512G FULLY PROTECTED HIGH SIDE POWER MOSFET SWITCH Features • • • • • • • Product Summary 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 Rds(on) 150mΩ (max) V clamp 50V I Limit 5A V open load 3V Description The IPS511G/IPS512G 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 7oC below Tshutdown. A diagnostic pin is provided for status feedback of short-circuit, overtemperature and open load detection. The double level shifter circuitry allows large offsets between the logic ground and the load ground. Truth Table Typical Connection Available Package Op.
