[ DS90UH928 ] Resistor for MODE_SEL

Kenichiro

Hi,

As for a resistor for MODE_SEL pin of DS90UH928-Q1, can I consider to be same as DS90UH926-Q1? See drawing below.

Thanks,

Ken

Yes. For the first level (target voltage = 0V) the resistor value is not as critical as the other levels.

Thanks,

HI Jason,

Sorry, let me revert this query.

If I want to set MODE_SEL and IDx of DS90UB(H)925/6, DS90UB(H)927/8 to No1,

(ideal ration = 0, ideal pull-down resistor voltage (R2 or R4) = 0)

0ohm resistor can be used as pull-down resistor. Correct?

Thanks,

Ken

Hi Ken,

Yes, 0 Ohm is fine in this case. I would still recommend putting the pads for pull-up so that you could use a different mode later on if needed.

Thanks,
Jason

Thanks, Jason! it's clear for me!

Have a good evening!
