• Manufacturer Part Number: bcm59101
• Description: Bcm59101 - Quad Integrated Ieee 802.3af-compliant Controller
• Manufacturer: Broadcom Corp.

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.
The BCM59101 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 BCM59101 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 BCM59101 is designed and tested to withstand cable
discharge events as well as ESD events in excess of 2 kV.
