Power Over Ethernet (PoE) Controllers

The MAX5984AETI+ is an integrated advanced power over Ethernet (PoE) controller that is used to manage advanced power over Ethernet systems. This advanced device features the ability to measure power delivery and the PoE port status, as well as provide AC line short-circuit protection and over-current monitoring.

The controller is an ideal choice for applications that demand tight control and full flexibility of their power and data networks. With its extended power management capabilities, this device can achieve high efficiency, while providing robust control and reliable operation of the advanced power over Ethernet systems.

Application Field

The MAX5984AETI+ is suitable for use in a variety of advanced power over Ethernet systems. It is suitable for use in equipment such as IP video security cameras, SmartGrid devices, medical devices, connected home routers and switches, VoIP phones, access points, and office automation devices. By providing a reliable and stable power management system for these devices, the MAX5984AETI+ offers a cost-effective power solution.

Working Principle

The MAX5984AETI+ is a dual-channel PoE controller that works by providing output control and power delivery. When connected to an Ethernet cable, the device will first measure the voltage on the Ethernet cable to determine if it is receiving power over the cable. If there is no voltage present, the device will then measure the current draw of the attached device to determine if it is receiving sufficient power to operate. If the current draw is too high, the controller will reduce the power output until the current consumption is within allowable limits.

When the device is connected to an Ethernet cable that is receiving power, the controller is able to act as a switch and distribute the incoming power between the two channels. The device is able to act autonomously, meaning that it can detect how much power is required by each device and automatically adjust the power output accordingly. This ensures that each device is receiving the correct amount of power without any manual intervention.

The MAX5984AETI+ also provides AC line short-circuit protection. This is important for preventing damage to the connected devices if the Ethernet cable is exposed to external EMI. This protection feature ensures that the connected devices will not be damaged by short circuits or overvoltages due to interference.

The device also features an integrated over-current detection circuit. This detects if any of the connected devices are drawing too much current and flags an error if this is detected. This feature helps to ensure that the connected devices are not damaged by excessive current consumption.

The MAX5984AETI+ is a highly integrated solution for advanced power over Ethernet systems. It is an ideal choice for applications that demand tight control and full flexibility of their power and data networks. With its extended power management capabilities and reliable operation, the device provides a cost-effective solution for advanced power over Ethernet systems.
