The LTC4252BIMS-2#TRPBF is a versatile IC (Integrated Circuit) component manufactured by Linear Technology (now a part of Analog Devices), suitable for use in Power over Ethernet (PoE) applications. This IC provides advanced power management features and an extensive range of protections to ensure reliable and safe power delivery.
One of the key features of the LTC4252BIMS-2#TRPBF is its ability to support both IEEE 802.3af and IEEE 802.3at standards, making it compatible with a wide range of PoE-enabled devices. It can deliver up to 25.5W of power to the connected device.
The IC offers two main operating modes: "PolyFuse" and "Auto-Restart." In the PolyFuse mode, it provides robust current limit protection by limiting the output current in case of a fault condition. The Auto-Restart mode automatically resumes power delivery after a fault condition has been resolved, making it suitable for applications that require continuous power delivery.
To ensure the safe operation of the system, the LTC4252BIMS-2#TRPBF incorporates various protection mechanisms. It provides input voltage monitoring, output voltage and current monitoring, over-temperature detection, and protection against short-circuit conditions. Additionally, it features a customizable input undervoltage lockout (UVLO) that can be adjusted to meet specific system requirements.
The IC also offers flexible control options
