Hi,
By using DRV104 to drive, my question is how long the OFF time needed in order to get designed delay time from DC mode to PWM mode.
This is our circuit design.
A 1uF capacitor connected to Delay Adju pin, so the DC to PWM delay will be 1/1.24 = 800mSec.
It is correct in single ON run, 780msec is near 800msec designed timing.
But if the off duration is shorter, It will not get 800msec delay; For example in below oscilloscope wave form, the time of DC is only 392msec.
