We are designing a PD device using TPS2373-4. Found the power output only last for 4 seconds then turn off and start again. Please help what is the root cause for such issue. The PSE chip connected is TPS23881, system is in BT mode.

Hi Liquan,

Thanks for reaching out!

- Could we have your PD schematic? If you do not want to share it in E2E I can reach out in email.

- Could you measure the TPS2373-4's VDD-VSS waveform at startup?

- Could you extract the TPS23881's register to check the failure root that PSE turns off the port?

Best regards,

Diang
