MAX5980GTJ+T Description

Short technical summary and product information.

The MAX5980GTJ+T from Analog Devices (formerly Maxim Integrated) is a quad-channel Power Sourcing Equipment (PSE) controller that adheres to IEEE 802.3at and 802.3af standards. This device is engineered for Power-over-Ethernet (PoE) systems, providing essential functions such as powered device (PD) discovery, classification, current limiting, and load disconnect detection.

 

Key electrical specifications include support for 32V to 60V operation, delivering up to 70W per port when Class 5 is enabled. It features a 0.25Ω current-sensing resistor and 9-bit monitoring for port current and voltage. The device offers both fully automatic operation and software programmability via an I2C-compatible, 3-wire serial interface, enhancing system flexibility and enabling field diagnostics.

 

Designed for ease of integration, the MAX5980GTJ+T is available in a space-saving 32-pin TQFN (5mm x 5mm) power package with an exposed pad. It operates within an automotive temperature range of -40°C to +105°C. This controller is suitable for applications such as PSE-ICM, switches, routers, and midspan power injectors.
