Just got sla 7062m board ready, and did some testing..... now i got a problem. Can´t get vref lower than +2.15vdc.. i try to use 1Amp motor, so i think i must get 0.25 to vref to be correct, a´m i right? i have those sense resistor .47 ohm 5W.
i really dont know where to star to solve this one.
i got 29V input, via zener so at lm317T i got 5.2 at output (middle leg) at 74hc14 i got 5.2. sla has 5.2 in leg nro 6.
I didn´t got bss92 so i used bss84 at lover side of pcb. i have gate of bss84 at next from 74hc14.
Can some one help me here?
