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
