Smart Highside High Current Power Switch

Reversave



• Reverse battery protection by self turn on of

power MOSFET

Features

• Overload protection

• Current limitation

• Short circuit protection

• Over temperature protection

• Over voltage protection (including load dump)

• Clamp of negative voltage at output

• Low ohmic inverse current operation

• Diagnostic feedback with load current sense

• Open load detection via current sense

• Electrostatic discharge (ESD) protection

• Green product (RoHS compliant)

• AEC qualified

Application

• Power switch with current sense diagnostic

feedback for up to 48 V DC grounded loads

• Most suitable for loads with high inrush current

like lamps and motors; all types of resistive and inductive loads

• Replaces electromechanical relays, fuses and discrete circuits

General Description

N channel vertical power FET with charge pump, current controlled input and diagnostic feedback with load

current sense, integrated in Smart SIPMOS chip on chip technology. Providing embedded protection functions.
