Protective Functions

•

•

Reverse battery protection without external components

•

Short circuit protection with latch

•

Overload protection

•

Multi-step current limitation

•

Thermal shutdown with restart

•

Overvoltage protection (including load dump)

•

Loss of ground protection

•

•

Electrostatic discharge protection (ESD)

Diagnostic Functions

•

Proportional load current sense (with defined fault signal in case of overload operation, overtemperature

shutdown and/or short circuit shutdown)

•

Open load detection in ON-state by load current sense

Applications

•

µC compatible high-side power switch with diagnostic feedback for 12 V grounded loads

•

All types of resistive, inductive and capacitive loads

•

Most suitable for loads with high inrush currents, so as lamps

•

Replaces electromechanical relays, fuses and discrete circuits
