Hall input to coil output
The phase relationship between the Hall input signals and the output current and voltage is shown in Fig.9. The motor
position data input via the Hall pins is amplified by the Hall amplifier, and formed into waveforms by the matrix
block.These signals are input to the output driver that supplies the drive current to the motor coils.
