Did you leave any pins floating? Unconnected CMOS inputs will not have a defined value, and they are often sensitive enough that stray electric fields can influence the state.
Ignorant me!
Just set up Brake "High-z" and thinking i dont need a brake. But indeed, i left pin (Vsens - pin 13) therefore floating. It does not have a pull-up resistor. Strangly it uses a resistor to GND to set up start configuration. It also matches my observation, that touching it on the vsense pin region, it was more often reproducible.
Now that whole case gets interesting:
- Can i somehow send a little boost on the DVDD line to make it work?
- Will it work, and not stop at any time?
It would have been awesome, if i would have been able to use the DVDD that is right next to it. But Vsense has an open drain mosfet. So i might have to get a bit creative.
