PGOOD_ is set to 1 (Table 14) at the end of the power-
up startup period if the power-good condition is met (0

PGOOD_. PGOOD_ is reset to 0 whenever the output
falls out of the power-good condition. A fault condition
immediately forces PGOOD_ low.
A3, A2, A1, A0 (Table 15) represent the four LSBs of
the MAX5952 address (Table 4). During a reset, the
device latches into R11h. These four bits address from
