Function

14
FRC
Capstan motor forward/reverse
control. This pin determines the
direction (forward or reverse) of the
capstan motor. (This input has
hysteresis characteristics.)
15
STBY
0 to VCC1
Selects the bias supply for all the
capstan motor circuits other than the
FG comparator. Setting this pin low
cuts off the bias supply. Thus it
functions as the standby mode control
pin.

LOCK
0 to VCC1
The output phase is locked by
applying a low to high trigger voltage
(edge) to this pin. This prevents the
motor from turning due to the
application of an external load in the
motor stopped state.

VCC2
3.5 to 6V
Power supply used for the source side
pre-driver voltage and the coil
waveform detection comparator.
1
VCC1
2.7 to 6V
Power supply used for voltages other
than the motor voltage, the source
side pre-driver voltage, and the coil
waveform detection comparator.
13
GND
Ground used for all systems other
than the output system.
