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 ips521/ips521s data sheet no.pd 60158-h description the ips521/ips521s 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 con- trolled 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 junc- tion 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. packages product summary r ds(on) 80m ?
