The LT4294HMS#TRPBF is a single-port, high-efficiency Power-over-Ethernet (PoE) power management integrated circuit (PMIC). This integrated circuit acts as a bridge between the data port of an Ethernet connection and the power port, providing management and power conversion from the Ethernet port to the power required for proper device operation. This integrated circuit is a highly efficient, low power solution for PoE applications.

The LT4294HMS#TRPBF is designed to provide power from an Ethernet port with up to 25.5W of output power and support for up to 12V of output voltage. The integrated circuit also supports multiple detection modes, including the standard IEEE802.3af PoE standard, as well as several proprietary modes, such as Cisco Proprietary Mode. This circuit also supports power level detection (PLD) and power management in both IEEE802.3af and Cisco Proprietary Mode. Additionally, the integrated circuit supports interoperability with other PoE controllers.

The LT4294HMS#TRPBF supports a wide range of power input and output. With its integrated voltage regulator, the circuit is capable of operating over a range of input voltage of 10V to 28V. The output voltage can also range from 0V to 12V, allowing the integrated circuit to support a wide range of applications. Additionally, the integrated circuit is protected against short circuits, overvoltage, and overcurrent conditions.

The integrated circuit also includes a number of features to support authentication and security. The circuit is protected against tampering and unauthorized access of data, as well as overload and underload conditions. Additionally, the integrated circuit\'s power detection and management feature uses the Ethernet link\'s light intensity to detect the presence of power in order to provide stability and efficiency.
