ture, ESD protection, inductive load capability and
diagnostic feedback. The over-current protection latches
off the device if the output current exceeds Ishutdown.
It can be reset by turning the input pin low. The over-
temperature protection turns off the high side switches
if the junction temperature exceeds Tshutdown. It will
automatically restart after the junction has cooled 7 o C
below Tshutdown. A diagnostic pin is provided for status
