BCM59101

•

Highest integration that allows for

• Lowest total BOM count

• Easier PCB placement and PCB area saving

• Full functionality without external u-controller including

• Eliminates the need for an external 48V to 3.3V power

Further reduces BOM count via 3.3V DC:DC capability to be

shared across multiple BCM59101 devices

Enables support of POE PDs such as emerging Wi-Fi

security cameras, and IP phone via 15.4W per port capability

Eliminates the need for a heat sink in IEEE 802.3af mode via

no-dissipation-Rsense and DC:DC to 3.3V

Makes layout and design easy via simple ground/power plane

Works with Broadcom POE-enabled products for easy

implementation

Architected with system-oriented features to allow for system-

level differentiation, including:

• Single point of interface for host hardware and software

• Power management across all ports in cascaded configuration

• Programmable current limits and dynamic measurement per

• Rapid power-down to support multiple power supply failures

Supports a variety of applications:

• Routers and switches for Enterprise, SMB, SOHO, and

• Ethernet midspans

• PSE power injectors

• Integrated magnetics
