Pin function
Coil waveform detect comparator
input pins.
Motor coil midpoint input pin.
Using this voltage as a reference,
the coil voltage waveform is
detected.
U, V, W phase coil output pins.
Drum motor driver output
transistor ground.
Constant
current drive is performed by
detecting the voltage at this pin.
Output midpoint control.
Oscillation prevention capacitor
connection pin.
When High, this pin sets CSLP
slant to 15 times the slant at Low.
When VCC1 = 3.0V
2.0V or higher: High
0.7V or lower: Low
