Hi,
I have solved the last days some issues with SPI communication and the last days I made the first attempt to connect a motor to my PCB. But it is not working and I attached the oscilloscope on SHB and SHC.
I fake the Hall sensors with my controller and I have this output for INHB and INLB:
The Output on the SHB and SHC is the following, I have a strange triangle and SHB and SHC are identical. :
If I change in PWM 3x Mode then I have the following output, SHB looks better but I have also a slope about 1ms, I cannot explain it:
This is my configuration,
as i said in previous post, my mosfet has Qgd 12.3nC and Qg 125nC
Could someone please explain me why in 1x Mode I have this confused behavior ?
And why in 2x PWM Mode I have so slow transition?
King Regards,
Nikos
