VCC2
3.5V to 6V
Power supply for supplying source side
predriver voltage and coil waveform detect
comparator voltage.
Common for loading, capstan, and drum
motors.
Power supply for circuits except motor
voltage, source side predriver voltage, and
coil waveform detect comparator voltage.
Common for loading, capstan,
and drum motors.
Connection for the triangular wave
generator. The coil output waveform is
made to operate in a soft switching manner
by this triangular wave.
