BCM59101 - Quad Integrated IEEE 802.3af-Compliant Controller

Quad Integrated IEEE 802.3af-Compliant Controller

The BCM59101 is a highly integrated quad power source equipment (PSE) controller compatible with IEEE 802.3af-2003. 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.

The BCM59101 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.

  • Supports IEEE 802.3af-2003 classification scheme and pre-IEEE 802.3af-2003 legacy detection in addition to being IEEE 802.3af-2003-compliant
  • Integrated switches, current sense functionality, microcontroller, AC and DC disconnect options
  • Highest integration that allows for low total BOM count, easier PCB placement, full functionality without external u-controller, eliminates the need for an external 48V to 3.3V power conversion
  • Enables support of PoE PDs such as emerging Wi-Fi® APs, security cameras, and IP phone via 15.4W per port capability
