XS2184 is a four-channel Power Sourcing Equipment (PSE) power controller with integrated power MOSFETs, designed for IEEE 802.3at/af compatible PSE applications. The device provides Powered Device (PD) detection, classification, current limiting, and load disconnect detection. It supports both automatic and software programming modes, along with two-event classification. The chip operates on a single power supply and includes large capacitor detection for traditional PD designs.
