Introducing the TPS23881RTQR Ethernet PoE PSE Controller by Texas Instruments

The TPS23881RTQR is a state-of-the-art octal Power over Ethernet (PoE) Power Sourcing Equipment (PSE) controller designed and manufactured by Texas Instruments (TI). This advanced integrated circuit is engineered to facilitate the delivery of power alongside data over Ethernet cables in accordance with the IEEE 802.3bt standard, also known as PoE++ or 4-Pair PoE. This standard allows for up to 90W of power per port, enabling a wide range of applications, from network cameras and wireless access points to IoT devices and lighting systems.

With its robust feature set, the TPS23881RTQR is designed to simplify the implementation of PoE solutions by integrating multiple functions into a single chip. The device includes an eight-channel PSE controller, supporting up to eight PoE ports, with per-port power management and an advanced power management algorithm that ensures efficient power allocation and prioritization across all ports.

The TPS23881RTQR offers enhanced flexibility and control with programmable power limits, allowing for precise power budgeting to meet the needs of various applications. It also includes comprehensive diagnostic capabilities and protection features, such as over-current, under-current, and thermal protection, ensuring reliable and safe operation under a wide range of conditions.

Designed for ease of use, this PSE controller is compatible with both Type 1 (15.4W) and Type 2 (30W) PoE devices, as well as the higher-powered Type 3 (60W) and Type 4 (90W) devices. The TPS23881RTQR also features an I2C serial interface for communication with a host controller, enabling real-time monitoring and control of the power delivery process.

Available in a compact QFN package, the TPS23881RTQR is ideal for space-constrained applications, while its extended temperature range makes it suitable for deployment in a variety of environments. Whether integrating into a new design or upgrading an existing network infrastructure, the TPS23881RTQR from Texas Instruments represents a reliable and high-performing solution for powering next-generation PoE-enabled devices.
