0 to VCC1
Capstan motor driver U, V, and W phase
Hall element input/output.
IN1 > IN2 state for logic H
39
ANGLE
Hall input/output gain control. Insertion of a
resistor between this pin and ground
controls the gain.
44
VS_C
0 to VCC2
Power pin that determines the amplitude of
the outputs to the capstan motor.
The voltage applied to this pin must be
lower than VCC2.

Rf_C
Capstan motor driver U, V, and W phase
output.

VH+
41
VH-
Hall element bias voltage supply.
A voltage that is typically 0.85V is
generated between the VH+ and VH- pins
(when IH= 5mA).
37
FGIN-
FG comparator inverting input. There is no
internally applied bias.
38
FGIN+
0 to VCC1
FG comparator noninverting input. There is
no internally applied bias.
36
FGOUT_C
FG comparator output. There is an internal
20k
resistor load.
40
FRC_C
0 to VCC1
Capstan forward/reverse select pin. The
voltage on this pin selects forward or
reverse rotation. (with hysteresis)
19
STBY_C
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.
