... Status feedback Open load detection Logic ground isolated from power ground Description The IPS521G is a 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 I lim value. The current limitation is activated until the thermal protection acts ...
