LM25066: LM25066 PMbus

Part Number: LM25066

Hi team. I have a problem with the LM25066. The efuse works ok except the communication by PMBus. All the registers that I read give the value 0x00. Also the STATUS BYTE, the STATUS WORD and the Voltage and current registers gave a 0x00. Only the Capability register returns a 0x90.

On the other hand, the Operation register also works, when writing a 0x00 in it the efuse goes OFF, and by writing 0x80 puts the LM25066 ON.

Thank you very much for your help.
