产品信息

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.
