The 32 V to 60 V supply range covers the standard PoE voltage bus (typically 48 V nominal) with margin for cable drop and transient conditions. ## What the 15.4 W rating means for your system The 15.4 W maximum output power per channel is the full 802.3af Class 0-3 budget, which after cable losses delivers 12.95 W at the Powered Device (PD) input. This controller is sized for standard PDs such as IP cameras, VoIP phones, and wireless access points that draw under 13 W. The 1 mA supply current drawn by the controller itself is negligible in the system power budget — it adds less than 0.1 % overhead on a 15.4 W port. Because it is a single-channel device, a multi-port switch or midspan requires one MAX5922AEUI+T per port. For designs needing eight or more ports, a multi-channel PSE controller may reduce component count, but the single-channel approach offers per-port fault isolation and independent enable control. The 0.65 mm pin pitch is layout-friendly on a two-layer board with proper thermal management. The tape-and-reel (TR) suffix indicates reel packaging for pick-and-place; cut-tape (CT) options are also listed for prototyping or low-volume builds. For new designs, this part is a current, supported choice. No pin-compatible second source or direct cross-reference is listed from other manufacturers, so the BOM carries a single-source risk that can be managed through stock coverage at quote time.","metaTitle":"MAX5922AEUI+T Analog Devices PoE PSE Controller, 15.4 W","metaDescription":"MAX5922AEUI+T Analog Devices single-channel PoE PSE controller, 802.3af compliant, 15.4 W max, 28-TSSOP.
