Hi
I am working with drv8307. I am facing problem with V_HS and V_LS GDRV it is not switching properly. I have attached the DSO images of phase V voltage and both side gate wave form.

Hi Onkar,
What signal is Channel 1, 2, and 3? Can you zoom in to capture a few (two or three) V_HS cycles with respect to phase V and a few V_LS cycles with respect to phase V.
Please disconnect the load and use Phase U and Phase W to debug Phase V.
The three phases should be identical in operation. Please measure the phase V FETs against the phase U and phase W looking for different resistance from gate to source, gate to drain, drain to source, and source to drain.
