MAX5956AEEE+T - Maxim Integrated

The MAX5956AEEE+T is a cutting-edge, highly integrated power-over-ethernet (PoE) interface controller from Maxim Integrated that is designed to simplify the implementation of PoE in Powered Devices (PDs). This compact and efficient component is essential for a wide range of applications including IP phones, wireless access points, and security cameras.

This advanced controller is compliant with IEEE 802.3af standards, ensuring compatibility with other PoE equipment. It features an integrated power MOSFET and sense resistor, which significantly reduces the number of external components required for PoE applications. This integration not only saves board space but also lowers the overall cost of the design.

The MAX5956AEEE+T operates over a wide input voltage range and provides a seamless interface between the Ethernet port and the internal power management units of PDs. With its built-in signature resistor and programmable power classification, it can accurately determine the power requirements of the PD and communicate this information to the Power Sourcing Equipment (PSE).

One of the key advantages of the MAX5956AEEE+T is its enhanced thermal performance, which ensures reliable operation even under full power load conditions. The device is also equipped with multiple protection features, including over-current protection, under-voltage lockout, and thermal shutdown, which safeguard the PD from electrical damage.

The MAX5956AEEE+T is offered in a 16-pin QSOP package, which is ideal for space-constrained applications. Its surface-mount design is optimized for automated assembly processes, making it easy to integrate into a variety of products. The controller's robust design and Maxim Integrated's commitment to quality make it a reliable choice for designers looking to incorporate PoE functionality into their devices.

With its combination of integration, efficiency, and protection features, the MAX5956AEEE+T from Maxim Integrated stands out as a premier solution for powering next-generation networked devices through Ethernet cables.
