Pin Name
Hall signal input pins.
The high state is when IN + is greater
than IN - , and the low state is the
reverse.
An amplitude of at least 100mVp-p
(differential) is desirable for the Hall
signal inputs. If noise on the Hall signals
is a problem, insert capacitors between
IN + and IN - pins.
If input is provided from a Hall IC, the
common-mode input range can be
expanded by biasing either + or -.
Ground pin of the control circuit block.
Power supply pin for control.
Insert a capacitor between this pin and
ground to prevent the influence of noise,
etc.
Control input pin. When CTL pin voltage
rises, the IC changes the output signal
PWM duty to increase the torque output.
Setting pin for drive phase adjustment
limit.
This pin is used to limit the lead angle of
the drive phase. The lead angle is
limited to zero degrees when the voltage
is 1.5V or lower and the limit is released
when the voltage is 3.5V or higher.
FG3 : 3-Hall FG signal output pin.
8-pole motor outputs 12 FG pulses per
one rotation. In power saving mode,
high-level is output.
FG1 :1-Hall FG signal output pin.
8-pole motor outputs 4 pulses per one
rotation. In power saving mode,
high-level is output.
