PRODUCTION DATA.
The PMBus Address is selected using resistors attached to the ADDR0 and ADDR1 terminals. At power-up, the device applies a bias current to each address detect terminal. The measured voltage on each terminal determines the PMBus address as defined in Table 1. For example, a 133kΩ resistor on ADDR1 and a 75kΩ on ADDR0 will select PMBus address = 100. Resistors are chosen from the standard EIA-E96 series, and should have accuracy of 1% or better.
A short or open on either address terminal causes the PMBus address to default to address 126. To avoid potential conflicts between multiple devices, it is best to avoid using address 126.
Some addresses should be avoided; see Table 1 for details.
