Quad Integrated IEEE 802.3at-Compliant PSE Controller
The Broadcom BCM59111 is a highly integrated, IEEE 802.3at-2009-compliant Power Sourcing Equipment (PSE) controller with unsurpassed integration and flexibility. It contains four low-RDS (0.35Ω), high-voltage pass-FETs, each with a very accurate, lossless, proprietary internal current sense and an onboard microcontroller -all targeted to significantly reduce the complexity of Power over Ethernet (PoE) and Power over Ethernet Plus (PoE+) designs while easing PCB layout. The BCM59111 provides excellent protection under all possible fault conditions and overloads. It also supports two-event Classification for Type 2 (30W) applications.
The BCM59111 has a networking-oriented host interface, communicating via a 400 kHz Broadcom Serial Control (BSC) bus.
