Enter the PWM “L” pulse width of 1μs and measure the time TNC from PWM rise to the CR pin voltage of 4V.
* Note 3 : Output delay time measurement
VM = 45V, PH = “H”, CR = 0V
Measure the time TDO1 from PWM = “H”
→ “L” fall to the output fall to 5V and TDO2 from PWM = “L” → “H” rise to
the output rise to 40V. Measure these times for OUTA, OUTAB, OUTB, and OUTBB respectively.
