EV3924-U-00A

EV3924-U-00A evaluation board is designed to demonstrate the capability of MP3924. The MP3924 is a quad power-source equipment (PSE) power controller for IEEE 802.3af/at compliant power over Ethernet (PoE). MP3924 has all the functions of IEEE 802.3af/at, including detection, 1-event and 2-event classification, current limit and load disconnect detection. All the functions can work in automatic operation mode or software program mode through I2C control. MP3924 features with 9bit ADC converter for current/voltage monitor, special I2C interface for isolated controller communication, different current limit level and programmable system function. The MP3924 is available in 32-pin QFN 5mmx5mm package. Applications include PSE switches/routers, PSE midspan power injector and surveillance NVR and DVRs.
