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.
Extern adjustable current limitation.
Application
All types of resistive, inductive and capacitive loads
µC compatible high-side power switch with diagnostic feedback for 12 V grounded loads
Due to the adjustable current limitation best 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)
Stable behaviour at low battery voltage

Positive power supply voltage.
Design the wiring for the
simultaneous max. short circuit currents from channel 1 to 2 and
also for low thermal resistance
Current limit adjust,
the current limit for both channels can be
chosen as high ( potential < 2V ) or low ( potential > 4V ).
