【产品】支持PoE,PoE +PSEs,4端口以太网供电控制器,适用于网络音频应用
SILICON LABS(芯科科技)是领先的芯片、软件和解决方案供应商,可为用户提供定制及通用产品,包括高性能混合信号的微控制器产品、时钟及晶振、隔离及电源产品、音视频产品、无线产品,其屡获殊荣的技术正在塑造物联网、互联网基础设施、工业自动化、消费电子和汽车市场的未来。
Si3452是一款由Silicon Labs(芯科科技)推出的一款4端口以太网供电控制器。当直接连接到主机系统或配置为自动模式时,每个Si3452以太网供电控制器都能为四个完整PSE端口的高压接口提供所有关键电路和复杂的功率测量功能。Si3452完全集成了坚固的低RON(0.3Ω典型值)的功率MOSFET,低功耗电流检测电路和瞬态电压浪涌抑制器件。片上电流检测电路和功率MOSFET提供可编程的电流限制比例,以匹配PoE(350 mA,15.4 W),PoE +(600 mA,30 W)和扩展(800 mA,40 W)的电源要求。设计用于PSE(例如,以太网交换机)或PSE(例如,内联电源注入器)应用,每个Si3452还执行IEEE所需的受电设备(PD)检测,分类和断开功能。
对于灵活的架构,可使用Silicon Labs专有的dV/dt算法来实现受电设备断开检测。dV/dt断开是直流断开的替代方案,不需要额外的BOM组件,不会耗散额外的设备电源,并且可以与所有受电设备完全互操作。其还提供了多点检测算法和每端口电流和电压监控。智能保护电路包括电源欠压锁定(UVLO),端口输出电流限制和短路保护,热过载检测和端口关断,以及瞬态电压浪涌抑制器,智能端口管理的故障源报告,这些都能够保护Si3452免受RJ-45接口上出现的各种恶劣浪涌事件的影响。同时,为了最大限度地提高系统设计灵活性并降低成本,每个Si3452都通过I2C串行接口直接连接到系统主机控制器,无需外部MCU。Si3452可以设置为12个唯一地址,允许在单个I2C总线上控制多达48个端口。此外,其采用40引脚的QFN封装(尺寸为6×6mm2),体积小,结构紧凑,符合RoHS标准,无铅,扩展温度范围为-40~85℃,电源电压范围为3.0~3.6V,电源电流范围为8~14mA,使其能应用于多种苛刻工作环境中,稳定性强。可用于网络音频、IP电话系统等应用。

PoE供电标准有哪些?
为了规范和促进PoE应用的发展,2003年6月,IEEE 802.3工作组制定了IEEE 802.3af标准,作为以太网标准的延伸,对网络供电的电源、传输和接收都做了细致的规定。IEEE 802.3af标准是基于以太网供电系统POE的新标准,它在IEEE 802.3的基础上增加了通过网线直接供电的相关标准,是现有以太网标准的扩展,也是第一个关于电源分配的国际标准。IEEE在1999年开始制定该标准,最早参与的厂商有3Com, Intel, PowerDsine, Nortel, Mitel和National Semiconductor。但是,该标准的缺点一直制约着市场的扩大。直到2003年6月,IEEE批准了802. 3af标准,它明确规定了远程系统中的电力检测和控制事项,并对路由器、交换机和集线器通过以太网电缆向IP电话、安全系统以及无线LAN接入点等设备供电的方式进行了规定。IEEE 802.3af的发展包含了许多公司专家的努力,这也使得该标准可以在各方面得到检验。2009年10月,IEEE 802.3at标准应大功率终端的需求而诞生,在兼容802.3af标准的基础上,提供更大的供电需求,满足新的需求。
IP Camera(网络摄像机)产品使用POE供电,采用了POE芯片Si3402,发现Si3402无电压输出,没有按照12V设计输出的原因是什么?
可能有以下原因:PD接的负载小于0.5W,如果小于0.5W也会没有输出,在POE协议中,会认定没有PD负载,PSE自动关闭这个端口的供电。因此需要在IP Camera上,把Si3402输出端的负载加上,总功耗超过0.5W,Si3402 12V输出正常了。

【应用】Silicon Labs新型802.3bt 90 W PoE产品组合实现广泛的路由器和交换机新用例
Silicon Labs推出的新型802.3bt 90 W PoE产品组合可实现广泛的路由器和交换机用例,使用该IEEE兼容以太网供电设备,可轻松为路由器和交换机以太网端口增加高达90W的功率。
PD控制芯片Si3402的评估板上特征电阻为什么要求是24.3KΩ?
PD的特征电阻要求是25KΩ±5%(23.75KΩ~26.25KΩ)。相应的PSE可以接受19KΩ至26.5KΩ较宽的电阻范围。24.3KΩ是针对于Si3402B的demo,考虑了寄生串联和并联电阻以及Si3402B内部阻抗的影响给出的数值。
以太网供电(POE)的受电端电源芯片(PD)Si3402,其评估板是按照5V电压输出设计,如果要实现12V输出,应该如何实现?
可以通过以下方式实现:1、如果要修改Si3402的输出电压,修改部分电路参数即可:变压器参数,输出电压反馈电路参数,滤波电容等。 2、在评估板的用户手册“Silicon Labs Si3402 ISO-EVB评估板使用说明”第10页,详细列出了5V,9V和12V电压输出的参数。
