)

• Electrostatic discharge (ESD) protection

Application

• Power switch with current sense diagnostic

feedback for 12 V and 24 V DC grounded loads

• Most suitable for loads with high inrush current

like lamps and motors; all types of resistive and

inductive loads

• Replaces electromechanical relays, fuses and

discrete circuits
