Tool/software:

Hi support team,

I think "TUSB320I EN high" is a typo.


Are there plans to fix this?

    Hi,

    The TUSB320 comes in 3 variants:

    The TUSB320: EN-N (active low) is the only option for enabling device

    TUSB320LAI: EN-N (active low) is the only option for enabling device

    TUSB320HAI: EN (active high) is the only option for enabling device

    This is as intended, albeit it could be clearer. Ill have a look when we will do our next revision of the datasheet and include this.

    Hi Vishesh,
    Thank you for your reply.

    Since TUSB320IRWBR is "Enable signal; active low", I think the description of "TUSB320I EN high" in SLLSEN9F is incorrect.

    Best regards,
