IPS521 High Side Power Mosfet Switch transistor socket 3 pin Fully Protected
Features
• Over temperature protection (with auto-restart)
• Short-circuit protection (current limit)
• Active clamp • E.S.D protection
• Status feedback
• Open load detection
• Logic ground isolated from power ground IPS521/IPS521S Data Sheet No.PD 60158-H
Description
The IPS521/IPS521S are fully protected five terminal high side switches with built in short-circuit , overtemperature, 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-temperature protection turns off the high side switch if the junction temperature exceeds Tshutdown. It will automatically restart after the junction has cooled 7o 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.
