General Description
The MAX5971A is a single-port, power-sourcing equip-
ment (PSE) power controller designed for use in IEEE
®
802.3af/at-compliant PSE. This device provides powered
device (PD) discovery, classification, current limit, and
DC and AC load-disconnect detections. The MAX5971A
operates automatically without the need for any software
programming and features an integrated power MOSFET
and sense resistor. The device also supports new Class 5
and 2-event classification for detection and classification
of high-power PDs. The MAX5971A provides up to 40W
to a single port (Class 5 enabled) and still provides high-
capacitance detection for legacy PDs.
The MAX5971A provides input undervoltage lockout
(UVLO), input overvoltage lockout, overtemperature
detection, output voltage slew-rate limit during startup,
and LED status indication.
The MAX5971A is available in a space-saving, 28-pin
TQFN (5mm x 5mm) power package, and is rated for the
extended (-40NC to +85NC) temperature range.
