LM5073HE-EVAL [Texas Instruments]

The LM5073 integrates a fully IEEE 802.3af compliant PD interface with versatile auxiliary power support. It features a 100V hot-swap MOSFET, programmable DC current limit up to 800mA, integrated PD signature resistor, PoE input UVLO, inrush current limit, PD classification capability, thermal shutdown, line over-voltage protection, and complementary open-drain outputs for DC-DC converter control. The device supports auxiliary power from unregulated sources like AC adapters and solar cells, with flexible configuration options for dominant/non-dominant power selection.
