This IC has an adjustable dead time feature and it mentions that the dead time appears when INa and INb go from high to low or vice versa. However, this is not happening. I have connected a 100K resistor at the DT pin and I have connected a 100 nF capacitor across it. I am receiving a waveform in which a dead time of 1 us is observed only when the INa goes from high to low and INb goes from low to high. When the situation is reversed I am not getting the desired dead time.
I have attached the image that shows the variation of dead time. It is correct for only one case i.e. when the INa goes from high to low and INb goes from low to high. Am I missing something ?
Also I am carrying out this testing at 15 V of VCC, VDDA and VDDB. Also the DC link voltage given when capturing this waveform was 0V.
