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
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
Basic Functions
Very low standby current
CMOS compatible input Improved electromagnetic compatibility (EMC) Fast demagnetization of inductive loads Stable behaviour at under
voltage Wide operating
voltage range Logic ground independent from load ground
Protection Functions
Short circuit protection Overload protection Current limitation Thermal shutdown Over
voltage 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)
