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
Product Summary Rds(on) Vclamp I Limit Open load Package 120m max. 70V 5A (typ.) 3V
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 7C 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.
