Power supply pin for fixing the output amplitude. Must be lower
than VCC2 voltage.
Power supply pin for amp circuit other than motor driver
transistor. Power supply pin for supplying voltage to other than
the control section whose supply voltage is VCC1.
Power supply pin for supplying voltage to the hall amp, forward
/reverse control, FG amp, thermal shutdown circuit.
When this pin is grounded, all the circuitry stops operating.
In this case, the supply current is approximately 100
μA. In the
normal operation mode, this pin is left open or made to be at a
potential of more than 2V.
The hall input-output gain (slope of motor waveform) can be
changed by changing the resistance connected across this pin
and GND.
FG signal input pin.
FG amp output pin.
FG schmitt amp output pin.
Pin for forward/reverse control of motor
L level : Forward (Less than 1.2V : When VCC1=5V)
H level : Reverse (More than 2.8V : When VCC1=5V).

Pin for stopping the motor
L level : Motor drive (Less than 0.8V).
H level : Motor stop (More than 2.0V).
