Power Over Ethernet (PoE) Controllers

NCP1082DEG

Power Over Ethernet (PoE) controllers enable Ethernet users to transfer power and data over the same cable without the need of external power supplies. The NCP1082DEG is one such type of PoE controller, developed by ON Semiconductor. It is a power-management integrated circuit (PMIC) designed specifically to provide reliable, high-performance PoE solutions for Ethernet applications.The NCP1082DEG provides reliable, efficient power distribution for up to two isolated ports, each delivering up to 15 Watts of power, making it perfectly suited for industrial and IP cameras, wireless access points, and other Ethernet-enabled devices. It also provides quiet, efficient operation and fast shutdown to keep your Ethernet devices operating safely and without interruption.The NCP1082DEG supports the universal PoE format PoE+ (IEEE802.3at) and the standard PoE (IEEE802.3af) protocols. It is designed to allow the host device to detect if the desired power is present, and to allow power negotiation between the power sourcing equipment (PSE) and the powered device (PD).The NCP1082DEG is designed to offer maximum flexibility when used in environments with mixed power requirements. It provides programmable current-limiting settings, allowing the system to safely turn off power to one port if it is overloaded, or to both ports if both overload. This ensures that the system will not be damaged if either port is drawing more than its allotted power.The NCP1082DEG features a soft start circuit which allows for a smooth ramp-up of the current level, avoiding inrush spikes when power is first enabled. This reduces the chance of damaging electrical circuits, devices and components.The NCP1082DEG also includes a short-circuit protection feature which will automatically shut off power to the ports if a short is detected. This ensures that the system does not suffer any damage due to a short circuit.The device also offers thermal and voltage monitoring and protection, ensuring that the system is not damaged if the temperature or voltage exceeds the specified operating range.In addition, the NCP1082DEG offers a wide range of fault-protection features, such as over-current protection, over-voltage protection, and over-temperature protection. These features ensure that the system is not damaged if any of these conditions occur.Overall, the NCP1082DEG is a highly advanced PoE controller that provides reliable, efficient power management and protection for your Ethernet-enabled devices. It is a great choice for applications where power, performance, and reliability are a must.
