Diagnostic Function
•
Proportional load current sense (with defined fault
signal in case of overload operation, overtemperature shutdown and/or short circuit shutdown)
Application
•
Power switch with current sense diagnostic feedback for 12V and 24 V DC grounded loads
•
All types of resistive, inductive and capacitive loads
•
Replaces electromechanical relays, fuses and discrete circuits
General Description
