Broadcom BCM59121B0KMLG

Контроллер (PSE)30 W802.3at (PoE+), 802.3af (PoE)

Overview

The Broadcom® BCM59121B0KMLG is a highly integrated IEEE 802.3bt-compliant power sourcing equipment (PSE) controller with unsurpassed integration and flexibility. It contains eight low-RDS (0.2Ω), 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+) and UPoE designs while easing PCB layout. The BCM59121provides excellent protection under all possible fault conditions and overloads. It also supports two-event Classification for Type 2 (30W) applications and multi-event Classification for 802.3bt Standard Type3 applications.The BCM59121B0KMLG has a networking-oriented host interface, communicating via a BSC bus and capable of speeds up to 2.4 Mb/s
