Design Of Automotive Power Trunk Lift Motor Drive
This guide design illustrates how to operate a trunk or rear gate lift in a vehicle.A brushed DC (BDC) lift motor and electromagnetic clutch drive mechanisms are used in this design for a traditional gear-driven lift.A alert beeper, light-emitting diode (LED) indicator, and directional control using an automobile motor driver and high side switch are all part of the specification.Boost MOSFET performance and minimise switching spikes with a current-controlled gate driver with slew rate modulation. The MOSFET's drain-to-source voltage (VDS) is used for current sensing. The electromagnetic clutch allows the user to manually work the trunk with this configuration. For flexible microcontroller use, this specification contains the standard gui using the TI Launch Pad development kit. As compared to relay solutions, this design provides a simple, robust implementation with a low component count and little board room.
