Problem with dual VNH2SP30 motor driver

Hi guys!

I got trouble with one of the drivers from my dual VNH2SP30 motor driver board.
It always outputs 100% of the input voltage (12v) even without PWM input (tied to ground).
The other driver works well with the same inputs and both used to work perfectly for a time.

Do you have an idea on this problem?


The two sides should be the same, so if you’re sure you’re doing the same thing with both and one is not working, it’s probably damaged. You might still check what the error outputs are doing. Did it work for you before, and if so, what happened when it stopped working?
