Pin Description
Pin function
Capstan motor driver U, V, W
phase Hall element input/output
pins. Logic High means IN1 > IN2.
Capstan motor output amplitude
control power supply pins.
Voltage must be lower than
VCC2.
Capstan motor driver U, V, W
phase output pins.
Hall element bias voltage supply
pins. A voltage of 0.85V (typ.) is
generated between VH+ and
VH– (at IH = 5 mA).
Pin voltage
0 to VCC1
0 to VCC2
