TUSB8041A: Request for a missing parameter in datasheet : USB VBus Monitor detection valid theshold.

around 0.35v.

Hi Brian, thank you for the prompt feedback, can you please also provide precisely the min / typ / max for this parameter? Because we suspect some devices to be near 0.45v for this threshold detection and we need to get the exact values to help our investigation.

Yanick:

    This is very old device and we can't find original validation data, so we can't get min/ttyp/max data.

 So you can not change external resistor to get higher voltage?

Yes we can change the external resistors divider but we were looking for the exact data before doing so. If you don't have the data for this we'll find another way to work this out thank you.

Yanick

The min and max is provided in TUSB8041A datasheet as shown below.

Thanks

Hi David, thank you however it is not the value I'm looking for. This is the allowable voltage range on the input but I'm looking for the exact threshold value with a min/typ/max for detecting a valid VBUS value (the voltage threshold for input low (0) vs input high (1) ). It is probably a voltage comparator input, we need to know what is the comparator reference voltage and tolerance.

Yanick

I am sorry for my misunderstanding.

I went and looked for this information on USB_VBUS and but not able to find it either.

Thanks

David
