The integrated internal switch eliminates the need for an external MOSFET, reducing BOM count and board area in compact switch or midspan designs. ## Supply voltage and power delivery Operating from a 32 V to 60 V supply rail, the device directly connects to standard PoE power sources (48 V nominal) with headroom for cable drop. The 40 W maximum power supports 802.3at Type 2 powered devices, including pan-tilt-zoom cameras, wireless access points, and thin clients. The 2.5 mA supply current keeps the controller's own dissipation low, important for thermally constrained enclosures. Housed in a 28-WFQFN exposed pad package with a 5x5 mm 28-TQFN supplier device package, the MAX5971AETI+T suits surface-mount assembly with a thermal pad for heat sinking. Analog Devices lists the MAX5971AETI+T as Active with ROHS3 compliance, indicating no near-term end-of-life risk for ongoing designs or production runs.","metaTitle":"MAX5971AETI+T Analog Devices PoE+ Controller, 40 W, 28-TQFN","metaDescription":"MAX5971AETI+T single-channel PSE controller, 40 W max, 802.3at/af compliant, 32-60 V supply, -40 to 85°C, active production.
