FCircuit operation

(1) 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.
