Description

The DRV8308RHAT is a 3-phase BLDC Motor Pre-driver with integrated speed control and commutation logic. It drives the gates of 6 external N-channel MOSFETs with a configurable current of 10mA to 130mA for optimal switching characteristics. The 3 motor phases are commutated according to the Hall sensor inputs. Once the motor reaches a consistent speed, the DRV8308 uses just 1 Hall sensor to minimize jitter caused by sensor mismatch. The Hall signal-to-drive timing can be advanced or delayed in 0.1% increments to optimize power efficiency. An optional 180° commutation mode drives sinusoidal current through the motor and minimizes audible noise and torque ripple. Peak motor current can be controlled by sizing a sense resistor. The driver achieves closed-loop speed control to spin motors to a precise RPM across a wide range of load torques. The system matches motor speed generated from an FG trace or the Hall sensors to the reference frequency on pin CLKIN.
