Smart High-Side Power Switch
●Four Channels: 4 x 90mΩ
●Status Feedback
●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
●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
●• Very low standby current
●• 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
●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 Function
●• Diagnostic feedback with open drain output
●• Open load detection in OFF-state
●• Feedback of thermal shutdown in ON-state
