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.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
