General Description
• N channel vertical power FET with charge pump, ground referenced CMOS compatible input, monolithically
® ^{integrated in Smart SIPMOS technology.}
• Providing embedded protective functions.
• Green Product (RoHS compliant)
• AEC Qualified
Application
• μC compatible power switch for 5V, 12 V and 24 V DC applications
• 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
• Optimized static electromagnetic compatibility (EMC)
• μC and CMOS compatible
• Fast demagnetization of inductive loads
• Stable behaviour at undervoltage
Protection Functions
• Short circuit protection
• Current limitation
• Overload protection
• Thermal shutdown
• Overvoltage protection (including load dump) with external
GND-resistor
• Reverse battery protection with external GND-resistor
• Loss of ground and loss of Vbb protection
• Electrostatic discharge (ESD) protection
Diagnostic Function
• Diagnostic feedback with open drain output
• Open load detection in OFF-state
• Feedback of thermal shutdown in ON-state
