The TPS23882B1RTQR from Texas Instruments is an advanced Power over Ethernet (PoE) Power Sourcing Equipment (PSE) controller IC designed to facilitate the delivery of power to multiple devices over a standard Ethernet infrastructure. This component is engineered to support the deployment of systems in accordance with the latest IEEE 802.3bt standard, allowing for up to 90W of power per port. It is capable of autonomously managing up to eight ports, providing a scalable solution for powering devices such as security cameras, wireless access points, and VoIP phones directly through Ethernet cabling. The TPS23882B1RTQR enhances system reliability through sophisticated power management, including detection, classification, and power-up sequencing while incorporating comprehensive protection features like over-temperature, over-current, and short-circuit protection. Its integration capabilities and efficient design simplify the development of Ethernet switches, injectors, and midspans, making it an essential component for networked power solutions. Housed in a compact QFN package, the TPS23882B1RTQR is designed for space-efficient layouts in PoE-enabled networking equipment.
