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 Ilim value. The current limitation is activated
until the thermal protection acts. The over-tempera-
ture protection turns off the high side switch if the
junction temperature exceeds Tshutdown. It will au-
tomatically restart after the junction 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.
