Re: MCP236 damaged when turned on/off

I measured the voltage of the power supply over time when switching the controllers on. I usually initially set the voltage to 12V and current to 0A, and then increase the current to a value that allows both the controller and motors to run without any issue. As I do that, and depending on how fast ...

Re: MCP236 damaged when turned on/off

Thank you for your fast reply. I am not driving anything with the motors, they are rotating freely. Also, the motors were not used when the issue happened, I just turned the controller on and off a few times to adjust some settings in BasicmicroMotionStudio - max current the motors can draw (1.6A), ...

MCP236 damaged when turned on/off

Hi all, I think I am doing something wrong with some MCP236 controllers, but cannot figure out what, so I would like to ask for your help. I have 3 MCP236, had some issues with 2 of them in the past, and now have an issue with one, for the same reason I think. My setup is as follows: I have a contro...

Re: Quadratic encoders - voltage issue

I've added some 2.2k pullup resistors on the 2 encoder channels and it raises the voltage enough now for the controller to detect it.
Thank you very much for your fast reply and your help, this was very useful!

Quadratic encoders - voltage issue

Hello, I am using a MCP236 Brushed DC Motor Controller, and have issues to read quadratic encoder inputs. The controller is powered by 12VDC on the B- and B+ pins. I am connected to the controller via USB, and have this motor plugged into it: https://www.pololu.com/product/3497 with this encoder att...
