Dear All,,,

We are reviewing the product to apply to the power sink we are planning.

I have three questions that I am uncertain about in the review.

Question 1 :

This product supports PD Spec. What is it?

PD3.0 with PSS or PD3.0 without PPS or PD2.0 without PPS?

Question 2 :

On the Cypress homepage, this product supports Apple Charging (2.4A), which is described in the product feature.

However, if I look at the DATASHEET of that product,

I can't confirm that it supports Apple Charging (2.4A).

Please check whether this product supports Apple Charging or not???

Question 3 :

In the datasheet of the chipset, the D + / D- pin is left unconnected,

It is recommended to leave D + / D- pin unconnected on the datasheet of this product.
However, the reference schematic provided in the Evaluation Kit of this product is drawn
to connect the D + / D- pin of the chipset to the usb type-c connector.
What should I do with the D + / D- PIN of the chipset?

Thanks,

Hi ,

Kindly refer my comments as below:

1. PD3.0 without PPS.

2. It's not support Apple Charging (2.4A).

3. You could wire to Type-C interface or let's floating. Since the BCR is not use the D+/D- currently.

Best Regards,

Lisa
