DRV8307 Description
The DRV8307 is a three half-bridge pre-driver that drives six N-type MOSFETs 30 mA with a single power supply. Aimed at sensored three-phase brushless DC motors, the DRV8307 is driven by a single PWM input and supports integrated mutation logic with three Hall sensor inputs. A separate 5-V regulator is also included to be used to power Hall-effect sensors and other external ponents.
