IP808AR

Product Overview

IP808AR is an IC Plus 8-port Power Sourcing Equipment controller designed for IEEE 802.3af/at Power over Ethernet systems. The device integrates power, analog and logic circuitry, including eight independent PSE ports, power FETs, current sensing, thermal monitoring and power-management functions. With support for up to 36W per port, I2C control, built-in regulators and multi-device expansion, IP808AR is well suited for PoE switches, midspans, endpoint PSE equipment and industrial Ethernet power systems.

Applications

IP808AR can be used in Ethernet networking equipment requiring centralized delivery and management of electrical power over twisted-pair cabling. Typical applications include 8-port PoE switches, 24-port and larger managed PoE switches, midspan injectors, endpoint PSE systems, IP surveillance networks, wireless access-point power systems, VoIP infrastructure and industrial Ethernet installations. Multiple IP808AR devices can be connected through the I2C interface to implement larger multi-port PoE systems with global power management.
