AUIPS7081(R)(S)PbF
INTELLIGENT POWER HIGH SIDE SWITCH
Features
 Over temperature shutdown (with auto-restart)
 Short circuit protection (current limit)
 Active clamp
 Open load detection
 Logic ground isolated from power ground
 ESD protection
 Ground loss protection
 Status feedback
Description
The AUIPS7081(R)(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.
