L6470 OUTPUTS PROTECTION

Question asked by pinon.luis_alfredo on Feb 18, 2016

We have an issue related your stepper motor controller L6470.

We are working with two of your evaluation boards: EVAL6470H-DISC and EVAL6470PD and we had two critical situations with two boards, one of each. In those situations, the controller IC blew up. The main question is: Should we use some kind of outputs protection like TVS or fast recovery diodes?. I will waiting for a prompt response. Kind regards.
