General Description

• N channel vertical power MOSFET with charge pump, ground referenced CMOS compatible input and

diagnostic feedback, monolithically integrated in Smart SIPMOS



technology.

• Providing embedded protective functions

Applications

• µC compatible high-side power switch with diagnostic feedback for 12V and 24V grounded loads in industrial

applications

• All types of resistive, inductive and capacitve loads

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

• Replaces electromechanical relays, fuses and discrete circuits

Basic Functions

• Very low standby current

• CMOS compatible input

• Improved electromagnetic compatibility (EMC)

• Fast demagnetization of inductive loads

• Stable behaviour at undervoltage

• Wide operating voltage range

• Logic ground independent from load ground

Protection Functions Block Diagram

• Short circuit protection

• Overload protection

• Current limitation

• Thermal shutdown

• Overvoltage protection (including load dump) with external

resistor

• Reverse battery protection with external resistor

• Loss of ground and loss of V

protection

• Electrostatic discharge protection (ESD)

Diagnostic Function

• Diagnostic feedback with open drain output

• Open load detection in OFF-state

• Feedback of thermal shutdown in ON-state
