Description

The TPS23880 is an 8-channel power sourcing equipment (PSE) controller engineered to insert power onto Ethernet cables in accordance with the IEEE 802.3bt standard.  The eight individual power channels can be configured in any combination of 2-Pair (1-channel) or 4-Pair (2-channels) PoE Ports. The PSE controller can detect powered devices (PDs) that have a valid signature, complete mutual identification, and apply power.

Programmable SRAM enables in-field firmware upgradability over I2C to ensure IEEE compliance and interoperability with the latest PoE enabled devices. Dedicated per port ADCs provide continuous port current monitoring and the ability to perform parallel classification measurements for faster port turn on times. A ±3% accurate programmable port power limit provides the ability to expand the maximum power sourced above 90 W without exceeding 100 W while also making system level power management control more easy to implement and reliable. The Fast Shutdown (OSS) input provides up to eight levels of per port shutdown priority for applications requiring immediate disabling of multiple ports. The 255-mΩ current sense resistor and external FET architecture allow designs to balance size, efficiency, thermal and solution cost requirements. 

Port remapping and pin-to-pin compatibility with the TPS2388, TPS23881, and TPS23882 devices eases migration from previous generation PSE designs and enables interchangeable 2-layer PCB designs to accommodate different system PoE power configurations.
