IPS521

IPS521/IPS521S 

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

Description 

The IPS521/IPS521S are fully protected five terminal high side switch with built in short-circuit , 

over-temperature, 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.
