Other functions
CW/CCW
The direction of motor revolution can be selected by setting the input level to H or L. CW is H level and
CCW is L level. The CW timing chart is indicated in Fig. 3, and the CCW timing chart in Fig. 5.
Current limiter function
The current limiter converts the GND driver transistor source current into V
RS
through the external R
S
, and
controls GND driver transistor conduction based on a comparison of this voltage to Vref
2
. Vref
2
generates a
0.1 V
CC
2 voltage in pin open state. Vref
2
is generated by the voltage division between 27 k
and 3 k
resistances, and so the Vref
2
level can be readily reduced by attaching an external resistor. To prevent HIC
destruction in the event of motor lock, a current limiter can be enabled by setting Vref
2
at or below Io ave. If
no such protection is required, set Vref
2
between Io max and Io ave to limit rush current.
FG OUT
This pin outputs a square wave pulse proportional to one motor revolution, which can be used as the motor
servo-control PLL IC FG input signal. The square wave L level time t
1
is set by the time constant of C
F
and
R
F
connected to the TFG pin (Fig. 4).

Expression

is designed to be half that of fixed speed t

, but when an FV conversion circuit is connected to
the FG OUT pin, it is necessary to reduce the duty to under 50%. In this case, adjust R

as needed.
Precautions in drive
Start current (rush current)
The motor start Rs current waveform is shown in Fig. 6. Current peak I
OH
must not exceed Io max.

Position detect signal
Because signal input sensitivity V
H
is ±500 mV max, the level of the output signal (open collector) from the
Hall IC must be reduced through conversion. A sample of this circuit is shown in Fig. 7. The position detect
signal must be compatible with the motor phase winding even in the time chart state shown in Fig. 3, or the
motor may not revolve smoothly.
Motor phase winding current during braking
The motor phase winding current during braking must not exceed Io max even during peak, although several
times set current levels are input.
