Hi Beader,

would you give us a quick schematic check?

customer wonder why CC line has 10Kohm pull-down resistor on EVM? is that needed?

Hi Fred,

I will review and provide feedback by Friday, Feb 17th.

As for CC lines, there are jumper selectable pull down resistors used to test different features, for more information on this please read section 6 of the EVM User's Guide.

Very Respectfully,

Hi Beader,

got it.

I'll keep them using 220pF instead of resistor

Hi Fred,

I will still review by original timeline. I would recommend using 330pF, eliminates need for protection device.

Hi beader,

the Vbus cap was 22uF originally,

I already told them to change to 10uF

Hi Fred,

We recommend 10uF, but 22uF should be fine too. Other than that, the other items I did not have visibility in.
