MAX5971AETI+T Description

Short technical summary and product information.

The MAX5971AETI+T from Analog Devices / Maxim Integrated is a single-port Power Sourcing Equipment (PSE) controller designed for IEEE 802.3af/at compliant applications. This device offers up to 40W of power to a single port, supporting Class 5 power levels and legacy device detection.

 

Key features include integrated PD discovery, classification, and current limit functions, operating automatically without software programming. It incorporates an internal power MOSFET and sense resistor, simplifying design. The controller also provides input undervoltage lockout (UVLO), overvoltage lockout, overtemperature detection, and LED status indication for port activity.

 

Designed for space-saving integration, the MAX5971AETI+T is housed in a 28-pin TQFN (5mm x 5mm) power package. It operates within an extended temperature range of -40°C to +85°C, making it suitable for various industrial and networking applications.

 

Applications include single-port PSE end-point and power injector (midspan) systems, switches, routers, industrial automation equipment, and wireless LAN access points.
