MAX5971BETI+T

Overview

The MAX5971BETI+T is a single-port, 40W IEEE 802.3af/at Powered Device (PD) controller manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 32 V to 60 V and features programmable current limiting. The device supports I2C communication for configuration and monitoring. It functions as a hot-swap voltage controller with power failure detection capabilities. The component is housed in a TQFN-EP-28 surface-mount package and is rated for an operating temperature range from -40°C to +85°C.

Feature Summary

Supports IEEE 802.3af/at standards for single-port PoE applications
Integrates programmable current limiting and power failure detection
Enables system management via I2C interface

Applications

Single-port Power over Ethernet (PoE) endpoints
IEEE 802.3af/at compliant network devices
Hot-swap voltage control in telecom systems
