Part Number:TPS65982
Hello,
we are using the TPS65982 in DP alt mode. We are configured as a DFP_D and we supply 5V @ 1.5A on VBUS.
We are observing an issue with the AUX+/- pins where we are not measuring the correct DC voltage on the pins and as such are failing compliance. As far as I understand the 65982 it has an internal 100k pullup to 3V3 on AUXN and a 100kpulldown on the AUXp.
My feeling is that we have the TI part configured incorrectly.
We are currently going trhough compliance and we are failing the AUX DC voltage which might indicate we are not pulling up/down the right RPU resistors in the AUX MUX.
Let me know what information I can send you to assist in the debug. Is there someone who is a DP Alt mode specialist that can assist.
Regards,
Guy
