    Hello, 

    Thank you for bringing this to my attention.

    Please reference this image for the connection that the TMCS1133 datasheet is referencing. 

    We will fix this in the next datasheet update. 

    Best Regards, 

    Joe

    Thank you very much for the figure. All the versions of the TMCS1133 do not have a pin outputting VREF. In Figure 8-6 as well as in the evaluation board, there is a VREF pin. Will there be a version of the TMCS1133 with a Vref pin in the future? That would be a very helpful feature.

    Hi Juergen, 

    My Apologies, this would in fact be an external reference so not the same diagram I provided. 

    As of now this figure only applies to the TMCS1126 but the VOC threshold can be created from an external reference as well. 

    Best Regards, 

    Joe

    Hi Joe,

    o.k. - I understand. That's a pity. The access to the internal reference would be very helpful and avoid some problems related to temperature drift, offset, etc. Therefore, I would recommend making this reference available - especially since there is an unused pin anyways. Best, Juergen
