SI3402-A-GMR Product Details

The Si3402 integrates all power management and control functions required in a Power-over-Ethernet (PoE) powered device (PD) application. The Si3402 converts the high voltage supplied over the 10/100/1000BASE-T Ethernet connection into a regulated, low-voltage output supply. The optimized architecture of the Si3402 minimizes the solution footprint, reduces external BOM cost, and enables the use of low-cost external components while maintaining high performance. The Si3402 integrates the required diode bridges and transient surge suppressor, thus enabling direct connection of the IC to the Ethernet RJ-45 connector. The switching power FET and all associated functions are also integrated. The integrated switching regulator supports isolated (flyback) and non-isolated (buck) converter topologies. The Si3402 supports IEEE Std 802.3™ 2008 including the IEEE Std 802.3at-2009 amendment for the case of single-event classification. Standard external resistors connected to the Si3402 provide the proper 802.3 signatures for the detection function and programming of the classification mode. Startup circuits ensure well-controlled initial operation of both the hotswap switch and the voltage regulator. The Si3402 is available in a low-profile, 20-pin, 5 x 5 mm QFN package. While the Si3402 is designed for applications up to 10 W, it can be used for higher power applications (up to approximately 15 W). See also “AN313: Using the Si3402 in High Power Applications” for more information.
