Part Number: TPS549A20

Hi team,

My customer would like set TPS549A20 PMBus address to 0x26 (8bit).

I checked the datasheet, it can be set with 255k + 27k ohm, correct?

Thanks.

Hi,

Your resistor value is correct. However, the HEX address is 0x13h The LSB bit is either read or write. Even though LSB is part of the 8 bit, SMBUS specification does not specify the LSB as part of the actual 7b Address (i.e., bits A7-A0).

Thank you.
