PGOOD_ is set to 1 (Table 14) at the end of the power-
up startup period if the power-good condition is met (0
< (V
OUT_
- V
EE
) < PG
TH
). The power-good condition
must remain valid for more than t
PGOOD
to assert
PGOOD_. PGOOD_ is reset to 0 whenever the output
falls out of the power-good condition. A fault condition
immediately forces PGOOD_ low.
PWR_EN_ is set to 1 when the port power is turned on.
PWR_EN_ resets to 0 as soon as the port turns off. Any
transition of PGOOD_ and PWR_EN_ bits set the corre-
sponding bit in the power event registers R02h/R03h
(Table 8). A reset sets R10h = 00h.

A3, A2, A1, A0 (Table 15) represent the 4 LSBs of the
MAX5965A/MAX5965B address (Table 4). During a
reset, the device latches into R11h. These 4 bits
address from the corresponding inputs as well as the
state of the MIDSPAN and AUTO inputs. Changes to
those inputs during normal operation are ignored.
