Drum motor driver output.
Lowest potential of the drum motor driver output
transistor.
Constant-current control is implemented by detecting
this voltage.
The current limiter also functions by detecting this
voltage.

drum motor driver output block and coil waveform
detection circuit.

8 to 13.8 V
Motor coil midpoint input.
This voltage is used as the reference voltage in coil
voltage waveform detection.
Coil waveform detection comparator inputs.
These are connected to each of the phase outputs
though internal 10-k
resistors.
Triangular waveform generator capacitor connection.
The triangular waveform generated using this pin is
used to implement soft switching for the coil output
waveforms.
The value of the capacitor connected between this
pin and ground in the VCO circuit determines the
operating frequency range and the minimum
operating frequency.
