Product details

Single-channel PSE controller for 40 W PoE+

The MAX5971BETI+ is a single-channel Power Sourcing Equipment (PSE) controller from Analog Devices, compliant with both 802.3at (PoE+) and 802.3af (PoE) standards. It integrates the switching FET internally and delivers up to 40 W per port over a single Ethernet pair set.

Supply range and controller overhead

Operating from a 32 V to 60 V supply rail, the controller itself draws 2.5 mA typical — the overhead is negligible against the 40 W delivery budget.

Footprint and board integration

Housed in a 28-WFQFN exposed-pad package (5x5 mm, TQFN-28), the part mounts on a standard surface-mount land pattern.
