Power Over Ethernet (PoE) Controllers are engineered to provide power from a power sulfce to different Ethernet enabled devices. They facilitate communications and data exchange between Powered Devices (PDs) and Power-Sourcing Equipment (PSE) and are designed for the acquisition and distribution of power over the Ethernet cable. TPS2377D-1 is an ideal solution for various field and industrial applications manuagents requiring high-frequency operation. With its highly efficient, medium power and wide input voltage range, it is an excellent choice for Ethernet-based power delivery systems.

The TPS2377D-1 is an IEEE 802.3bt compliant Power-over-Ethernet (PoE) controller that operates in current-mode. It supports source and sink mode operation, enabling it to both source and sink current up to 60 Watts. The controller can be used in both a 4-pair and a 2-pair application, making it suitable for both low-power and high-power designs. The part supports a wide input voltage range of 2.39V to 60V.

The TPS2377D-1 features an enable input (EN) which is used to enable the PSE when enabled is pulled low. The PSE driver is capable of driving up to 2A of current. The output voltage may be set with an external resistor or the output voltage can be controlled using a feedback loop. The TPS2377D-1 also features an internal temperature monitor with protection against over-temperature conditions.

The TPS2377D-1 includes a current-mode Power Over Ethernet controller that provides a complete solution for the exchange of data and power over Ethernet cables. It provides a wide range of functionality, including synchronous rectification, a programmable current limit, and over-temperature protection. The controller is designed to provide constant current during PD power-sourcing and constant voltage during PD power-sinking operations. It is designed for PoE Plus systems and supports both 4-pair and 2-pair configurations. It also features an adjustable boost or buck output voltage range, programmable current limit, and over-temperature protection.

The TPS2377D-1 is versatile and can provide the infrastructure needed for many different types of industrial applications. It can be used to power remote access points in wireless networks, as well as medical systems, communication equipment, and other specialized equipment. It is well-suited for applications such as automation and industrial control, security systems, point-to-point communication links, and distributed power architectures. It could also be used in a wide range of consumer applications such as game consoles, set-top boxes, and other home entertainment systems.

The TPS2377D-1 is designed for easy integration into a wide range of applications. It features an integrated detection circuit for detection of a standard IEEE 802.3at/bt powered device, and is compatible with a wide range of regulatory requirements. It supports hot-swap and hotswap-detection, and 3-pin status LEDs for providing visual power status information.

The TPS2377D-1 is a highly integrated and cost-effective solution for the delivery of power and data over Ethernet. It is an ideal choice for many industrial and field applications requiring PoE capability and offers a flexible, reliable, and energy efficient power solution.
