The TPS23751PWPR is a power-over-Ethernet (PoE) controller designed to simplify the development of a variety of Ethernet applications. It is designed to provide power, data, and communications control to powered devices (PDs) through a single cable from a power source equipment (PSE). The device operates from an input voltage range of 48 V to 60 V and can deliver up to 30 W of power to the PDs.

The TPS23751PWPR device has two main features: a three-port Ethernet switch, and a power-over-Ethernet controller. The three-port switch provides bidirectional data transfer, while the PoE controller enables power and control communication between the PSE and PD. The device has five power-over-Ethernet (PoE) ports: one 24V, two 12V, one 6V and one 5V port. When the link is active, the device can provide up to 30 watts of power to the PDs and can also detect the required power and automatically adjust the output power accordingly.

The TPS23751PWPR device includes a unique auto-detect and auto-negotiate feature, which enables the device to detect the required power and immediately adjust the output power to match the PD’s capabilities. This feature reduces the overall system design time, since the on-board diagnostic capabilities support faster system implementation. The device also supports standard Ethernet protocols, ensuring compatibility with existing networks.

The main components of the TPS23751PWPR device are the voltage regulator, the control logic, the PoE controller and the Ethernet ports. The voltage regulator is used to control and regulate the power output from the PoE port to the PDs. The control logic is used to provide the power control signals between the PSE and the PDs. The PoE controller is used to detect and negotiate the required power from the PDs. Lastly, the Ethernet ports are used for communication and data transfers.

In addition to providing power, the TPS23751PWPR device also supports enhanced communication control functions. These functions enable users to perform real-time system monitoring and fault analysis, making the device ideal for IP telephony, industrial control and surveillance, and networking applications. The device is also certified to meet the Power Sourcing Equipment (PSE) standards specified by IEEE 802.3af and 802.3at, allowing multiple PDs to be powered, while securely protecting data integrity.

The TPS23751PWPR device is a powerful and cost-effective solution for enabling Power over Ethernet. Its comprehensive feature set provides maximum flexibility in system design and power delivery. With its high power-efficiency and easy integration, it is an ideal choice for powering PoE-enabled devices.
