MAXIM INTEGRATED / ANALOG DEVICES MAX5971AETIT Power Sourcing Controller
The MAX5971AETI+T is a single-port, 40W Power Sourcing Equipment PSE controller compliant with IEEE 802.3af/at standards. It features an integrated 28-pin TQFN package with a built-in MOSFET for efficient power management. Designed for Ethernet switches, routers, wireless access points, and industrial automation, it supports PD discovery, classification, current limiting, and load disconnect functions. It can deliver up to 40W to high-power PDs, including Class 5 support, with features like input UVLO, overvoltage, overtemperature, and slew rate control. Operating voltage is 32V–60V, temperature -40°C to 85°C, with a 0.5Ω integrated MOSFET and sense resistor. Supply current is around 2.5mA, and it provides LED status indicators and supports AC/DC load removal detection.
