This reference design is a small-footprint motor control module intended for sunroof and window-lift applications. This design uses the DRV8703-Q1 gate driver with an integrated current-shunt amplifier alongside two dual-package automotive-qualified MOSFETs to create a very small power-stage layout compared to typical relay solutions. It also includes two of our DRV5013-Q1 latching hall sensors, which are used to encode the motor position.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
