High-Power, Quad, PSE Controller

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 four LSBs of
the MAX5952 address (Table 4). During a reset, the
device latches into R11h. These four 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.
