Hi TI,
I have 2 DRV8842s on my board connected to 2 linear actuators as part of a product. The connection between the actuator and the DRV8842 on my board goes through a panel mount connector and a board connector. The actuators drove both actuators as expected one day, the next day I transported the product in a van maybe 30 miles later, and the actuators no longer worked. After a while, the actuators worked and then after more transport, 200 miles, the actuators stopped working again. The issue is not from the actuators or the wiring because when I swap boards the actuators work. It seems like the act of transport affects the driver.
I'm still to identify where the failure is, the outputs, inputs etc. but I wanted to ask the question to see if this issue has been seen before.
Thank you,
Louis
