INTELLIGENT POWER HIGH SIDE SWITCH
Over temperature shutdown (with auto-restart) Short circuit protection (current limit) Active clamp Open load detection Logic ground isolated from power ground protection Ground loss protection Status feedback
Product Summary Rds(on) Vclamp Limit Open load Package max. (typ.)
Description
IPS7081(R)(S)PbF five terminal Intelligent Power Switch (IPS) with built short circuit, over-temperature, protection, inductive load capability diagnostic feedback. output current limited Ilim value. Current limitation activated until thermal protection acts. over-temperature protection turns device junction temperature exceeds Tshutdown. will automatically restart after junction cooled below Tshutdown. diagnostic provided status feedback short circuit, over-temperature open load detection. double level shifter circuitry allows large offsets between logic ground load.
