... Status feedback Open load detection Logic ground isolated from power ground Description The IPS5451/IPS5451S are fully protected five terminal high side switch with built in short circuit, over-tempera- ture, ESD protection, inductive load capability and diagnostic feedback. The over-current protection latches off the device if the output current exceeds Ishutdown. ...
