This is a three-phase brushless DC motor drive designed to operate in 12-V automotive applications such as HVAC blowers. This reference design drives motors in the 200-W range and can handle currents up to 20 A. Utilizing either sensorless operation or external hall-effect sensors, the design provides the flexibility to adapt to many motors.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
