BCM59103

The BCM59103 is a highly integrated quad power source equipment (PSE) controller compatible with IEEE 802.3af-2003 and high power support. The controller is the industry first to offer a highly integrated architecture with revolutionary enhancements that are targeted at reducing the complexity of Power over Ethernet (PoE) designs. At 30W+ per port, the BCM59103 is also the industry first PSE controller to offer an integrated solution for higher power applications.

The BCM59103 integrates the microcontroller, power switches, low-loss current sense function, detection, classification, and voltage converters, 3.3V bias regulator (DC:DC converter) and AC disconnect functionality.

The high level of integration and innovation make the device the most power efficient integrated IEEE 802.3af PoE system.
