Description for the TPS23880

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.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

A custom reel is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.

Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.

TI often ships tube or tray devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
