TPS2321: Troubleshooting

Hi Andres,

Thanks for reaching out to us. We will get back to you by tomorrow. 

Hi Avishek,

Today we removed the FETs that were connected to the swap controller and replaced them with a short circuit. We did this because we thought those FETs might be causing the problem. We obtained these waveforms: yellow is 5V1, blue is fault, and purple is gate. There is a delay between the output and control signals.

This waveform shows full-load conditions with a current of 6A (it is also the same with No-Load)

However, the module that works properly shows that the control signals are activated before the output rises. This is the correct behavior, as the NFETs should be activated to deliver power to the output.

Hi Andres,

Sorry to say, I am not able to understand your issue. Can we talk tomorrow some time? If yes, I will share my email ID through private chat for sending the meeting request.

Ok no problem. If it's not too much trouble, would it be possible to have a confidential agreement in place before sharing any information about the schematic? This would help ensure that any sensitive information remains protected and only used for the intended purpose. Thank you for your understanding.
