The MAX5940DESA+T is an IEEE 802.3af-compliant Powered Device (PD) interface controller designed for Power-over-Ethernet systems. It provides essential functions including PD detection and classification signatures, an integrated isolation switch with programmable inrush current control, and undervoltage lockout (UVLO) with wide hysteresis.
This controller features a voltage input range of 39.9V to 67V and a maximum power rating of 12.95W. It operates reliably across an extended temperature range of -40°C to +85°C. The device includes an integrated MOSFET for PD isolation and inrush current limiting, and offers power-good outputs to enable downstream DC-DC converters.
Packaged in an 8-SOIC form factor, the MAX5940DESA+T is suitable for surface mount applications. Its design supports compliance with the IEEE 802.3af standard, making it ideal for applications such as IP phones, security cameras, and wireless access nodes that require Power-over-Ethernet connectivity.
