Product Introduction

Overview

The TPS23880RTQR, produced by Texas Instruments, is an 8-channel power sourcing equipment (PSE) controller designed to comply with the IEEE 802.3bt standard for Power over Ethernet (PoE) applications. This controller is engineered to insert power onto Ethernet cables, supporting both Type 3 and Type 4 PoE configurations. It features eight independent PSE channels that can be configured in any combination of 2-pair or 4-pair PoE ports, making it versatile for various high-power PoE applications.
