General Description
⢠N channel vertical power MOSFET with charge pump, ground referenced CMOS compatible input and
diagnostic feedback, monolithically integrated in Smart SIPMOS® technology.
⢠Fully protected by embedded protection functions
Applications
⢠µC compatible high-side power switch with diagnostic feedback for 5V, 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 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)
Diagnostic Function
⢠Diagnostic feedback with open drain output
⢠Open load detection in ON-state
⢠Feedback of thermal shutdown in ON-state
