Motor controller suddenly stop while in operation for 2 months in a AGV application. Even power led now working. According to multi meter there is the short circuit in 3.3V line. What are the components to check? There are not any physical damages visible.
There is no 3.3V line on the SBL2360, so I am not exactly sure what you are talking about. Do you know which pins there is a short between on the SBL2360?
