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 SIPMOSï
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
⢠CMOS compatible input
⢠Undervoltage and overvoltage shutdown with auto-restart and hysteresis
⢠Fast demagnetization of inductive loads
⢠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 Functions
⢠Proportinal load current sense
⢠Diagnostic feedback with open drain output
⢠Open load detection in OFF-state with external resistor
⢠Feedback of thermal shutdown in ON-state
