Automotive Power Trunk Lift Motor Drive Reference Design

Description

This design describes how to drive an automotive trunk lift or rear gate lift.In this design: a brushed BD lift motor and electromagnetic clutch drive mechanisms for a typical gear driven lift. This design includes a warning beeper: LED indicator: and directional control that uses an automotive motor driver and high side switch. A current-controlled gate driver with slew rate control helps improve MOSFET efficiency and decrease switching spikes.This design gives a simple: robust implementation with a low component count and small board space compared to relay solutions.

Features
  • Operated from 12-V automotive battery systemOutput power for lift to a mzimum of 360WOutput power for clutch to maximum of 48WLow power sleep mode less than 55µAOver-current and short-circuit protection through VDS sensing
Applications
  • Trunk module
  • Seat comfort module
  • Off-highway vehicles electric drive
