Product details

PoE PD controller for 802.3af powered devices

The MAX5942ACSE+ is a single-channel powered device (PD) controller compliant with the IEEE 802.3af PoE standard, delivering up to 12.95 W to the load over Ethernet cabling. Operating from an 18 V to 67 V supply rail, it draws only 400 µA of supply current, keeping the overhead low for the downstream DC-DC converter.

Package, mounting, and temperature grade

No internal switch is integrated — the controller drives an external MOSFET and sense resistor, giving the designer flexibility to match the switch to the load current.

Lifecycle and compliance status

No auxiliary sense input is provided — this is a basic PD controller for standard 802.3af applications without signature detection override.

Frequently asked questions

What is the MAX5942ACSE+ used for?

It is a powered device (PD) controller that negotiates power from an IEEE 802.3af PoE switch or injector and delivers up to 12.95 W to the load, suitable for IP cameras, wireless access points, and VoIP phones.

Does the MAX5942ACSE+ include an internal switching FET?

No, it requires an external MOSFET and sense resistor, allowing the designer to select the switch based on the application's current and thermal requirements.
