GND

Power supply pin for determining

output amplitude by supplying

drum motor voltage.

Must be lower than VCC2 voltage.

Power supply pin for supplying

source side predriver voltage and

coil waveform detect comparator

voltage. Common for loading,

capstan, and drum motors.

VCC1

Power supply pin for circuits

except motor voltage, source

side predriver voltage, and coil

waveform detect comparator

voltage.

Common for loading, capstan,

and drum motors.

Pins for connecting triangular

wave oscillator capacitor. This

triangular wave coil output

performs waveform soft switching.

1kΩ

13 14

Ground pin for all circuits except

output.
