MAX5987AETE+T Description

Short technical summary and product information.

The MAX5987AETE+T from Analog Devices is an integrated circuit designed as a Power Device (PD) controller for Power-over-Ethernet (PoE) systems, compliant with IEEE 802.3af standards for Class 1 and Class 2 operation. This device combines a PD interface with an efficient DC-DC converter, reducing the need for external components.

 

Key electrical specifications include a wide input voltage range of 8.7V to 60V and a maximum power handling capability of 6.49W. The device operates with a typical supply current of 3.6mA and supports programmable output voltages from 3.0V to 14V. It features integrated switches and auxiliary sensing capabilities.

 

The controller operates within a temperature range of -40°C to 85°C. It is housed in a 16-TQFN (5x5) package and is designed for surface mounting. The device also includes features such as a 1-channel configuration and supports 802.3af (PoE) standards.

 

This PoE controller offers a compact and efficient solution for powering devices over Ethernet networks, simplifying design and saving board space.
