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
Protection Functions
• Reverse battery protection with external resistor
• Short circuit protection
• Overload protection
• Current limitation
• Thermal Shutdown
• Overvoltage protection with external resistor
• Loss of GND and loss of V_bb protection
• Electrostatic discharge Protection (ESD)
