BCM59103

Quad Integrated IEEE 802.3at-Compliant Controller

The BCM59103 is compatible with IEEE 802.3at-2009. The controller is the first in the industry 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 802.3at POE system.

  • IEEE 802.3at-2009-compliant
  • High hardware integration with:
    - Integrated switches
    - Integrated current sense functionality
    - Integrated microcontroller
    - Integrated AC and DC disconnect options
  • Highest integration that allows for:
    - Lowest total BOM count
    - Easier PCB placement and PCB area saving
    - Full functionality without external u-controller including power management
    - Eliminates the need for an external 48V to 3.3V power conversion
  • Further reduces BOM count via 3.3V DC:DC capability to be shared across multiple BCM59103 devices
