MAX5988BETP+ is a Power-over-Ethernet (PoE) Controllers. It provides an efficient power delivery solution for both fast Ethernet ( IEEE 802.3bt Type 3) and Gigabit Ethernet (IEEE 802.3bt Type 4) systems. The power delivery system consists of two parts: a PoE controller (MAX5988BETP+ ) and a Power Sourcing Equipment (PSE). The PoE controller manages the incoming power of the PSE and provides a constant supply of power to connected devices.

The power delivery of the MAX5988BETP+ is highly efficient and consumes lower power than other PoE controllers. The MAX5988BETP+ utilizes an intelligent power tracking system that dynamically adjusts the voltage supplied to the connected devices based on the load current requirements. This ensures that the devices will always receive the optimal power for their needs. As a result, the MAX5988BETP+ can supply up to 15W of power to an individual port.

The MAX5988BETP+ also integrates a variety of interface options, enabling easy implementation of PoE systems. The controller supports both an I2C bus and a serial port for communication to the PSE as well as SPI and UART interfaces for device management. Additionally, it utilizes two proprietary protocol interfaces, one for data communication between the MAX5988BETP+ and PSE and the other for power management. The MAX5988BETP+ also features integrated voltage and current monitoring, providing real-time performance feedback to system operators.

The MAX5988BETP+ also provides high-level of fault detection and protection. The controller integrates a variety of safety features to prevent damage to connected devices or cables due to power surges or faults. The MAX5988BETP+ has built-in overcurrent and overvoltage protection, as well as a low-impedance short-circuit detector and a thermal-overload protection feature. All these features ensure that connected devices are kept safe and that your system remains up and running.

In addition, the MAX5988BETP+ implements innovative power-saving features such as support for IEEE 802.3az Energy-Efficient Ethernet (EEE) and low-power sleep modes, allowing the controller to reduce power consumption in idle states by up to 85%. This makes the MAX5988BETP+ ideal for applications that require high efficiency, such as remote PoE systems, battery-powered systems and low-power embedded applications.

The MAX5988BETP+ is an ideal solution for any high-power PoE application, providing a highly efficient and reliable power delivery system. Its advanced features, such as adaptive power tracking, comprehensive fault detection and protection and low-power operation make it an ideal choice for any power-sensitive application.
