General Description
•
N channel vertical power MOSFET with charge pump, ground referenced CMOS compatible input,
diagnostic feedback and proportional load current sense monolithically integrated in Smart SIPMOS
technology.
•
Fully protected by embedded protection functions
Applications
•
•
•
•
µC compatible high-side power switch with diagnostic feedback for 12V and 24V grounded loads
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
