voltage required to operate the driver.
Note2) If V
ref
is made lower than this voltage, the driver dose not operate.
Note3) Refer to the driver input/output characteristics chart.
Note4) If the PC pin voltage is made higher than this voltage, there will be no output voltage from the driver. Both (+
) and (–)
outputs are pulling in the current.
Note5) If the PC pin voltage is made lower than this voltage, the driver operates normally.
