Description

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.
