Interface between the 1-wire protocol and HDQ protocol, is it possible?

Rafael Souza

Hello Texas Instruments.

Is it possible to perform communication intergration between a device that uses only the 1-Wire communication protocol and a device that uses the HDQ communication protocol?
Are both protocols compatible with each other in any way?

Thank you, the support.

Hey Rafael,

I am not an expert on HDQ however I did find an app note:

www.ti.com/lit/an/slva101/slva101.pdf

This shows you can use UART and it also points out that a simple GPIO can be used to do this.

Hello Friend.

Thanks for your help, I had seen this document, but I really needed to know if there would be compatibility between the 2 protocols or some other form of communication between the two protocols.

Hey Raphael,

To me it looks like it would work if the bit rates were limited to the slowest limit (I think that is 1 wire protocol) but I do not have much experience with this so I will move this thread assignment internally to one of the Battery teams in TI who may know more about the HDQ protocol and if they are famillar with 1 wire protocol then they may be able to give you a solid yes/no answer you are looking for.

Hi Rafael,

I am not familiar at all with 1-wire, so I did a little research. It turns out 1-Wire and HDQ are completely different and are not compatible with each other.

If you do a quick google search of "1-wire vs. HDQ", there is lots of good information describing the differences and how to interface to both.

Best regards,

Matt
