Product Summary

Package

General Description

•

N channel vertical power FET with charge pump, ground referenced CMOS compatible input, monolithically

integrated in Smart SIPMOS® technology.

•

Providing embedded protective functions.

Application

•

µC compatible power switch for 5V, 12 V and 24 V DC 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
