The IPS511G/IPS512G/IPS514G are fully protected five terminal high side switches with built in short-circuit,over-temperature, ESD protection, inductive load ca-pability 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 junc-tion has cooled 7below 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.
