General Description

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

diagnostic feedback, monolithically integrated in Smart SIPMOS 80V technology.

• Providing embedded protective functions

• An array of resistors is integrated in order to reduce the external components

Applications

• µC compatible high-side power switch with diagnostic feedback for 12V and 24V and 42V grounded loads

• All types of resistive, inductive and capacitive loads

• Most suitable for inductive loads

• Replaces electromechanical relays, fuses and discrete circuits

Basic Functions

• 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

• Optimized inverscurrent capability
