Pin Name
Pin to select the forward/reverse type.
This pin goes to the high level when
open.
Pin to set the constraint protection circuit
operating time and initial reset pulse.
Insert a capacitor between this pin and
ground.
Insert a resistor in parallel with the
capacitor if the protection circuit is not to
be used.
External PWM input pin.
Apply an external PWM input signal to
this pin.
(Input frequency range is from 0.5 to
60kHz.)
PWM ON = Low
PWM OFF = High or open
HALL bias pin (3.6V output).
Connect an NPN transistor.
(See “5 Hall Input Signal.")
