The MAX5940DESA+ is an IEEE 802.3af-compliant Power Device (PD) interface controller designed for Power-over-Ethernet systems. It provides essential functions for PD compliance, including detection and classification signatures, an integrated isolation switch with programmable inrush current control, and undervoltage lockout (UVLO) with wide hysteresis.
This controller features a single channel and operates within a voltage range of 39.9V to 67V, with a power rating of 12.95W. It includes an integrated MOSFET for PD isolation and inrush current limiting. The device offers programmable inrush current control and operates over an extended temperature range of -40°C to +85°C.
The MAX5940DESA+ is supplied in an 8-SOIC package, suitable for surface mount applications. It is designed to work with or without an external diode bridge and includes power-good outputs to enable downstream DC-DC converters. Its features make it suitable for applications such as IP phones, security cameras, and wireless access nodes.
