Frequently Asked Questions
How much power can MAX5984AETI+ deliver per PoE port, and which IEEE standard does it follow?
The MAX5984AETI+ delivers up to 40W per port and complies with both IEEE 802.3af (up to 15.4W) and IEEE 802.3at (up to 30W) standards. Its integrated MOSFET handles switching internally, enabling a single-port PSE solution without requiring an external power transistor, simplifying the design significantly.
Over what input voltage range does MAX5984AETI+ operate, and how does this affect network switch design?
MAX5984AETI+ operates across an input voltage range of 5V to 57V, which accommodates typical 48V PoE power buses found in enterprise network switches. This wide range reduces the need for precise regulation at the board level and allows the device to tolerate line transients in industrial and telecom environments without requiring additional protection components.
For a compact IP camera injector design, what package does MAX5984AETI+ use and how small is its footprint?
MAX5984AETI+ is housed in a 28-pin 5x5 mm LFCSP (Quad Flat No-Lead) package, offering a very compact footprint compared to older DIP or SOIC PSE controllers. This allows the complete single-port PoE PSE circuit to fit on a small PCB area, making it ideal for compact wall-plate injectors, IP camera housings, and space-constrained industrial enclosures.
When should a designer choose MAX5984AETI+ over a multi-port PSE controller for a networking product?
MAX5984AETI+ is the preferred choice when a design requires 1 to 4 independent PoE ports on separate PCB sections, such as rack-mount media converters or small desktop switches, because each port can be powered and faulted independently using its own device. Multi-port controllers with 4 to 8 ports offer lower per-port cost at high volume but require a central power budget of at least 120W, which is unnecessary for small-port-count designs.
