MP3924 Quad-Port, IEEE 802.3af/at PSE Controller for Power over Ethernet DESCRIPTION The MP3924 is a quad-port power source equipment (PSE) power controller for IEEE 802.3af/at compliant power over Ethernet (PoE) applications. The device has all the functions of IEEE 802.3af/at, including detection, single-event and two-event classification, current limiting, and disconnected load detection. All of the functions can be configured to work in automatic operation mode or software program mode via the I2C. The MP3924 features a 9-bit analog-to-digital converter (ADC) to monitor the current and voltage, a special I2C interface for isolated controller communication, adjustable current limits, and configurable system functions. These features provide flexibility for PoE applications.
