General Description
• N channel vertical power MOSFET with charge pump, ground referenced CMOS compatible input and
diagnostic feedback, monolithically integrated in Smart SIPMOS

80V technology.
• Providing embedded protective functions
• An array of resistors is integrated in order to reduce the external components
Applications
• µC compatible high-side power switch with diagnostic feedback for 12V and 24V and 42V grounded loads
• All types of resistive, inductive and capacitive loads
• Most suitable for inductive loads
• Replaces electromechanical relays, fuses and discrete circuits
Basic Functions
• 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
• Optimized inverscurrent capability
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 V
bb
protection
• Electrostatic discharge protection (ESD)
Diagnostic Function
• Diagnostic feedback with open drain output and integrated
pull up resistors
• Open load detection in OFF-state
• Feedback of thermal shutdown in ON-state
• Diagnostic feedback of both channels works properly in case of inverse current
