Capstan motor driver U, V, and W phase
Hall element input/output.
IN1 > IN2 state for logic H
Hall input/output gain control. Insertion of a
resistor between this pin and ground
controls the gain.
Power pin that determines the amplitude of
the outputs to the capstan motor.
The voltage applied to this pin must be
lower than V CC 2.
Capstan motor driver U, V, and W phase
output.
Hall element bias voltage supply.
A voltage that is typically 0.85V is
generated between the VH+ and VH- pins
(when IH= 5mA).
FG comparator inverting input. There is no
internally applied bias.
FG comparator noninverting input. There is
no internally applied bias.
FG comparator output. There is an internal
20k resistor load.
Capstan forward/reverse select pin. The
voltage on this pin selects forward or
reverse rotation. (with hysteresis)
Pin to select bias supply to capstan circuits
other than FG comparator. Setting this pin
to low cuts-off the bias supply.
Capstan motor standby pin.
