Tool/software:
Hello,
I have a customer evaluating the TIDA-010261 SPE/PODL reference design for a new project and we have a question regarding the power/data interface that I'm hoping you can help to provide guidance on. See below!
Snipped below is the schematic section showing the power/data interface, I’m trying to understand the bridge rectification formed with D18,D19,D21,D22. If D20(TVS) was a unidirectional device, I would understand the need for rectification. Am I missing something? Couldn’t D20 simply be placed across Power/Data_P and Power/Data_N?
