does CYPD3175 power SDK I2C SCB block support i2c General Call Address ?
i didnt find any refernce to general call i2c https://www.cypress.com/file/175671/download
Show LessHi!
We have had some problem to support 20V/5A in our solution due to the challenge of practically implementing an exact current-protection at 5A. On one hand we need to support up to 5A so that certain laptops don't complain that there is not enough power, on the other hand for our CE-certification, Intertek compains that we should absolutely not provide more than 5A before over-current protection happends.
Is there any guidance in regards to which margins are available here? Or the hardware and software implementation needs to ensure that we hit 5.00A as max current?
Cheers

Show LessHi, I'm looking into using the CY4533 as a power barrel replacement and also use it's internal USB transceiver. Unfortunately there is no information in the datasheet about the use of the USB C Transceiver part. THe CY4533 kit has just a power component and no USB connections. The connections D- and D+ have a comment "leave unconnected".
Where can I find some more information about the Transceiver part of the CY4533?
Thanks, Paul
Show LessHi!
I know that PPS (source) is available in the SDK/lib for CYPD317x, but which other SKUs? We use CYPD4226 and CYPD312x and there is no support as far as we can see. We need to add PPS source to our dual-port dock design. Are there any dual-port SKU that supports PPS source on both ports?
Cheers

Show LessHello
The CCG3 data sheet has the following description on page 5.
>Integrated Billboard Device
>CCG3 integrates a complete full speed USB 2.0 device controller capable of functioning as a Billboard class device.
>The USB 2.0 device controller can also support other device classes.
>
Q1) Does this mean that i can use CCG3 to support device classes such as UVC without using a device controller such as FX2LP? Is it stated that CCG3 can be used as a USB 2.0 device controller?
">The USB 2.0 device controller can also support other device classes."
Q2) So, I would like to know more about the above datasheet contents.
Best Regards

Hi everyone,
I use in my project SDK CYPD3120-40LQXI_dp_dongle.
During connecting Provider and Consumer, Consumer enable N-channel MOSFETs. I understand this is a dead battery mode.
I want disable Dead Battery mode.
Could you help me?
Best regards,
Nazar
