Smart Highside Power Switch

Reversave



• Reverse battery protection by self turn on of

power MOSFET

Features

• Short circuit protection with latch

• Current limitation

• Overload protection

• Thermal shutdown with restart

• Overvoltage protection (including load dump)

• Loss of ground protection

charged inductive loads)

• Very low standby current

• Fast demagnetisation of inductive loads

• Electrostatic discharge (ESD) protection

• Optimized static electromagnetic compatibility

(EMC)

• Green Product (RoHS compliant)

• AEC qualified

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
