Description
The IPS7091(G)(S)PbF is a five terminal Intelligent Power
Switch (IPS) with built in short circuit, over-temperature,
ESD protection, inductive load capability and diagnostic
feedback. The output current is limited at Ilim value.
Current limitation is activated until the thermal protection
acts. The over-temperature protection turns off the device
if the junction temperature exceeds Tshutdown. It will
automatically restart after the junction has cooled 7°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.
