• Manufacturer Part Number: bcm59103
• Description: Bcm59103 - Quad Integrated Pre-ieee802.3at Controller With Power Management
• Manufacturer: Broadcom Corp.

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.
The BCM59103 offers a networking-oriented host interface that offers a
full suite of power management. This easy to use interface can be
extended to manage up to 64-cascaded ports through a single host
interface.
The BCM59103 is designed with robustness and legacy support. It offers
detection and classification mechanisms capable of detecting both IEEE
802.3af-compatible devices and legacy devices simultaneously. In
addition, the BCM59103 is designed and tested to withstand cable
discharge events as well as ESD events in excess of 2 kV.
