Maxim Integrated MAX5995BETE+ Ethernet Powered Device Interface

The Maxim Integrated MAX5995BETE+ is a sophisticated Power over Ethernet (PoE) powered device (PD) interface integrated circuit that is designed to simplify the implementation of PoE functionality in networked devices. This high-performance IC is compliant with the IEEE 802.3at (PoE+) standard, ensuring compatibility with a wide range of PoE power sourcing equipment (PSE) and providing up to 25.5W of power.

Featuring an integrated 0.5Ω MOSFET and sense resistor, the MAX5995BETE+ offers a complete solution for PDs requiring a high level of integration to reduce the footprint and complexity of the design. Its advanced features include programmable classification, inrush current limiting, and under/overvoltage lockout, which provide a high degree of protection and reliability for sensitive electronics.

The MAX5995BETE+ is housed in a compact 16-pin TQFN-EP package, making it ideal for space-constrained applications such as IP cameras, wireless access points, and VoIP phones. Its thermal performance is enhanced by an exposed pad that can be soldered to the PCB for improved heat dissipation.

Key features of the MAX5995BETE+ include:

• IEEE 802.3at (PoE+) compliance for seamless integration
• Integrated 0.5Ω power MOSFET to minimize external components
• Support for 2-event classification for power level negotiation
• Programmable inrush current limit and power-up time for design flexibility
• Overtemperature protection and thermal shutdown for device safety
• LED driver outputs for visual status indication
• Robust 100V absolute maximum rating on the HOT and RET pins

The MAX5995BETE+ is an ideal choice for designers looking to implement PoE capabilities with minimal design overhead and maximum protection for their PDs. Its robust feature set ensures that devices not only receive power safely over Ethernet cables but also maintain stable operation under various electrical conditions. Maxim Integrated's commitment to quality and reliability is evident in this product, making it a trusted component in any PoE-enabled device.
