TPS65994AD:  Compatibility Issue with TPS65994AD: VBUS Drop During Boot When Using Philips Display as 12V Power Source.

Hi,

Our team member will respond to this shortly.

Regards

Jack, could you share the logs in some other format? maybe csv?

in addition to that, can you please share a little more detail regarding

• what is the adcin configuration?
• where does the device load patch from?
• what are the sink PDOs?
• Whats the time difference between VBUS coming up and VIN3V3 coming up?

Varun，Thanks for your reply. I could not provide other format, but you can reference the attached screenshot. The timeline clearly indicates that the hard reset trigger occurs after full completion of PD communication.

1. ADC1 registers 2, while ADC2 registers 7 .
2. An external EEPROM is implemented – see the annotated diagram below for details.
3. The interval is approximately 10ms – refer to the waveform capture below.(Yellow trace: VBUS voltage, Blue trace: 3V3IN supply)

2 questions:

• Which firmware version are you using?
• The pass and fail logs show that you're using a different cable, is that correct? Is it happening only with a specific cable?
