The NCP1280DR2 is an integrated circuit component manufactured by ON Semiconductor. It is a versatile Power over Ethernet (PoE) controller designed for use in various applications that require data and power transmission over Ethernet cables.
One of the key features of the NCP1280DR2 is its ability to integrate multiple functions into a single chip, making it a cost-effective solution for PoE applications. The component incorporates a PD (Powered Device) controller, DC-DC converter, thermal protection, and various protection features, all in one IC.
The NCP1280DR2 is compliant with the IEEE 802.3at standard, also known as PoE+ or PoE Plus, which allows for up to 25.5 watts of power to be transmitted over Ethernet cables. This enables the component to provide power to devices that require higher power consumption, such as IP cameras, wireless access points, and VoIP phones.
To ensure reliable operation, the NCP1280DR2 offers comprehensive protection features. It includes built-in surge protection, overcurrent protection, and over-temperature protection, guarding against potential damage to the IC or connected devices. The thermal protection feature prevents excessive heat buildup by controlling the operating temperature within a safe range, improving overall system reliability.
The NCP1280DR2 also incorporates advanced communication functions for efficient power management. It supports multiple detection methods, including both legacy and new standards, ensuring compatibility with a wide range of PoE-enabled devices
