TPS65994AD: ADCIN1 and ADCIN2 settings

GI shim

Part Number: TPS65994AD

Tool/software:

When setting ADCIN 1:7 and ADCIN 2:5,
Is it set to 5V / 3A output?
Does 'PD' communication send SOUCE CAP and support the operation of EMCA CHECK or DP when set up as above.

I'm designing a USB4HOST controller.
Since there is a limit of current, I want to set ADCIN to limit the output current.
When setting up 5V/3A via ADCIN,
Is there a problem with PD communication?

Thank you.

Hi,

What reference design you are following for this USB4 host design? We do not recommend using TPS65994AD as this device is way too old in terms of the latest test standard.

It is being designed with ASM4242.
This is the circuit diagram I received from ASMEDIA.

Can I answer that?

Hi,

Please reach out to ASMedia on this as TPS65994AD is too old to pass compliance. This is likely a very old reference design from them and it was not updated.
