Hello,
I have this circuit which is partially working.
When I set the signal from the pic to LOW D32, D3 and D45 turn on and the output from U59 changes state.
The issue is when I try to turn it off, only D32 fully turns off. The gate of Q45 is therefore kept low thru the pull down.
But D3 and D45 remain on, slighlty, I tried adding a 10K pull up to the base of Q1, but that didn't help. Any input will be appreciated.
