Pin function
Drum motor forward/reverse
rotation select pin.
Low: forward
(–0.2V to 0.7V or open)
High: reverse
(2V to VCC1)
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.
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.
Ground pin for all circuits except
output.
Pin voltage
