Hi
I use DRV8840PWP on my design. But i have no voltage at the output. You can see my sch below.
- I see 3v3 correctly at the nSleep, nReset, Phase and Enable pins. ( As i apply )
- I se 3v3 correctly at the V3P3OUT.
- I see about 35V at the VCP.
However I see no voltage at the Output pins.
- I see 0V at Output1 to Output2
- I see about 1.5V at Output1 to GND
- I see about 0v at Output2 to GND.
