This design is a 3-phase sensored Brushless DC Motor controller that uses a single PWM input for controlling speed and three active-high hall sensors for rotor position detection. The DRV8305's integrated commutation table simplifies the microcontroller firmware required for proper commutation. The DRV8305 automatically handles dead time insertion and gate drive current control, both of which can adjusted using the drivers SPI interface.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
