MAX5953BUTM+T

Power Over Ethernet (PoE) Controllers are specialized devices that measure the power being transmitted over an Ethernet connection. The controllers detect the voltage, current, and power over the Ethernet cable, and then adjust the control output based on the measured values. The MAX5953BUTM+T Controller is one such device.

The MAX5953BUTM+T is designed for use in commercial and industrial Ethernet applications, such as Power over Ethernet (PoE). This device monitors the power being transmitted over Ethernet and prevents overloading or damaging equipment. It features a tight control loop that can detect small changes in the line voltage and current, and make corresponding adjustments to the output. The controller also protects against overheating and over-voltage conditions. The MAX5953BUTM+T also offers a range of power supply protection features, including over-temperature and overtemperature protection, overvoltage protection, short-circuit protection, and external reset circuit.

The MAX5953BUTM+T operates in either IEEE PoE or DC-DC Buck-boost mode. In the IEEE mode, the controller monitors the applied voltage and adjusts the output voltage to meet the IEEE 802.3at standard. The DC-DC Buck-boost mode allows the controller to achieve up to a 70% efficiency rating, while offering flexibility to support multiple output voltages. The MAX5953BUTM+T also offers frequency compensation and hysteresis control to ensure that the output voltage is precisely maintained.

The MAX5953BUTM+T features a wide switching range that allows for use in applications ranging from 25V to 100V. The controller can provide up to 5 Amps of output current and can operate at temperatures ranging from -40°C to +85°C, making it suitable for use in most industrial environments. The MAX5953BUTM+T also features built-in ESD protection, providing protection for components connected to the controller.

The MAX5953BUTM+T is a powerful, flexible, and reliable solution for ongoing monitoring and control of power over Ethernet connections. Its tight control loop ensures that changes in line voltage and current are detected, while its wide range of protection features help prevent damage or overloading of equipment. The device is also temperature-tolerant, allowing it to be used in most industrial applications. The MAX5953BUTM+T is an excellent choice for any application that requires precise and reliable control over power being transmitted over Ethernet connections.
