Maxim Integrated MAX5965BUAX Ethernet Power Controller

The MAX5965BUAX from Maxim Integrated is a sophisticated power controller designed to deliver power over Ethernet (PoE) as per the IEEE 802.3af/at standards. This highly integrated device is an essential component for networked equipment such as wireless access points, IP cameras, and VoIP phones, enabling them to receive power along with data over standard Ethernet cables, thereby reducing the need for additional power supplies or outlets.

The MAX5965BUAX is packaged in a compact, 36-pin SSOP (Shrink Small Outline Package), which makes it suitable for space-constrained applications. It operates over the -40°C to +85°C extended temperature range, ensuring reliable performance in various environments.

One of the key features of the MAX5965BUAX is its ability to perform inrush current limiting, overload, and short-circuit protection, which safeguards both the power sourcing equipment (PSE) and the powered device (PD) from electrical mishaps. The device's auto-classification function allows it to detect the class of the PD and deliver the appropriate power level, up to a maximum of 30 watts for high-power devices.

The MAX5965BUAX also comes with an integrated power MOSFET and sense resistor, which simplifies the design and reduces external component count. Its built-in I2C-compatible serial interface enables system-level communication for remote control and monitoring, providing enhanced control over the PoE functions.

For designers and engineers looking to integrate PoE capabilities into their products, the MAX5965BUAX is an excellent choice due to its ease of use, high integration, and compliance with the latest PoE standards. Moreover, its robust protection features and efficient power management capabilities make it a reliable and energy-efficient solution for any PoE application.

Maxim Integrated's commitment to quality ensures that the MAX5965BUAX meets the high standards required for network power applications, making it a trusted component for manufacturers and system integrators who demand the best in power delivery technology.
