General Description
N channel vertical power MOSFET with charge pump, ground referenced CMOS compatible input and
diagnostic feedback, monolithically integrated in Smart SIPMOStechnology.
Providing embedded protective functions
Applications
µC compatible high-side power switch with diagnostic feedback for 5V, 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
Fast demagnetization of inductive loads
Stable behaviour at undervoltage
Wide operating voltage range
Logic ground independent from load ground
Protection Functions
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 Vbb protection
Electrostatic discharge protection (ESD)
