General Description
The MAX5969D provides a complete interface for a
powered device (PD) to comply with the IEEE
?/DIV>
802.3af/
at standard in a power-over-Ethernet (PoE) system. The
MAX5969D provides the PD with a detection signa-
ture, classification signature, and an integrated isolation
power switch with inrush current control. During the
inrush period, the MAX5969D limits the current to less
than 180mA before switching to the higher current limit
(720mA to 880mA) when the isolation power MOSFET
is fully enhanced. The device features an input UVLO
with wide hysteresis and long deglitch time to compen-
sate for twisted-pair cable resistive drop and to assure
glitch-free transition during power-on/-off conditions. The
MAX5969D can withstand up to 100V at the input.
The MAX5969D supports a 2-event classification method
as specified in the IEEE 802.3at standard and provide a
signal to indicate when probed by a Type 2 power sourc-
ing equipment (PSE). The device detects the presence
of a wall adapter power source connection and allow a
smooth switch over from the PoE power source to the
wall power adaptor.
The MAX5969D also provides a power-good (PG) signal,
two-step current limit and foldback, overtemperature pro-
tection, and di/dt limit. The MAX5969D is available in a
16-pin, 5mm x 5mm TQFN power package. This device is
rated over the -40NC to +85NC extended temperature range.
