Hi all,
I checked the 3V3 rail and noticed the following:
- Input voltage of VSYS 4.2V injected is seen on the input cap
- The output is 0V on the output caps, also showing a short on both caps to GND.
- The console when connected to my Bench PSU and activating the power on the PSU shows 0A current draw. I should expect 0.001-0.005A but it is flat zero
I don't think it is the 77801 that is the issue, but I have trouble following through, what to check. My IR cam does not show anything getting hot (which is expected given no power draw)
