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
