PRODUCTION DATA.
The Buck-Boost converter in DAC8771 has a read only bit called power good (PG) (address 0x0B Table 5). This bit is set to logic '1' when both of the following conditions are met
The PG bit indicates the status of the outputs of the enabled Buck-Boost converter. For example, if the positive and negative outputs of the Buck-Boost converter are enabled, then the PGA bit is set to a logic '1' only after the positive output pins of the Buck-Boost converter are ≥ 4 V and the negative output pin of Buck-boost converter is ≤ -3 V.
