is the input high state, and the reverse is the input low state.
Connect a capacitor between the IN

and IN
–
inputs if there is noise in
the Hall sensor signals.
An amplitude of over 50 mV p-p and under 350 mV p-p is desirable in
the Hall sensor signals. Kickback may occur in the output if the input
signal has an amplitude greater than 350 mV p-p.

OUT1
Motor drive outputs
Connect capacitors between the motor outputs (or between the motor
outputs and ground) if oscillation occurs in the outputs. (Use capacitors
in the range 0.1 μF to 0.47 μF.)

Output current detection
Connect a resistor (Rf) between this pin and ground.

Stabilized power supply output (5-V output)
Connect a capacitor (about 0.1 μF) between this pin and ground for
stabilization.

XI
Crystal oscillator connections
These pins are used to drive the reference clock oscillator element.
If an external clock (with a frequency of a few MHz) is used, connect a
resistor (about 13 k
) to the XI pin in series and input the clock signal
through that resistor. Leave the XO pin open in this case.
