Product details

PoE+ PD controller for powered-device designs

The MAX5969BETB+T is a single-channel Power-over-Ethernet (PoE) Powered Device (PD) controller from Analog Devices, compliant with both 802.3af (PoE) and 802.3at (PoE+) standards. It integrates the internal switching MOSFET and delivers up to 25.5 W to the load, making it suitable for high-power PDs like IP cameras, wireless access points, and VoIP phones that draw the full PoE+ budget.

What the 25.5 W rating means for your BOM

The 25.5 W maximum power delivery corresponds to the full Class 4 (802.3at) allocation from a PSE. This means the controller can support loads that require the entire PoE+ budget — a typical dual-radio 802.11ac access point drawing 18-22 W still has headroom for the controller's own 270 µA supply current and the auxiliary sense circuit. The 40 V to 60 V supply range covers the full PoE voltage envelope from the PSE output, including the 44-57 V range typical after cable drop. The internal switch eliminates an external FET, saving board space in the 10-TDFN (3x3 mm) package.

Active production, ROHS3 compliant

It is ROHS3 compliant, meeting the latest EU directive for lead-free and restricted-substance materials.

Frequently asked questions

What is the MAX5969BETB+T used for?

It is a PoE+ PD controller that negotiates power from a PSE (Power Sourcing Equipment) over an Ethernet cable and delivers up to 25.5 W to the load. It integrates the internal switch and auxiliary sense, so it is used in powered devices like IP cameras, wireless access points, and VoIP phones that need the full PoE+ budget.
