【应用】专为符合Telcordia GR-1089室内标准要求而设计的POTS电话线保护解决方案
本方案包括三种类型的接地参考普通电话(POTS)正极和负极接口,接地参考应用常与电话线的电话总机端有关。 大多用户终端设备(CPE)保护方案都不属于接地参考型。 POTS(普通老式电话服务)线路传送正常的电话语音信号。 振铃时,电压可达275伏。 这些解决方案还可用于大部分ADSL应用设备(最大频率1.1 Mhz)。
LITTELFUSE提供一系列SIDACtor® 、TeleLink或PTC解决方案。 下图所列的是几种常用的解决方案。使用PTC或LFR后,该保护适用的器件可降低至“B”类器件。 许多器件都可提供DO-214/Compak 封装。 在电路板空间有限的情况下,P6002CBL是一种绝佳的解决方案。 在许多ITU K.20应用中,都可使用“A”类器件。
方案一使用Littelfuse推出的P1800SCL SIDACtor保护晶闸管和04611.25表面贴装保险丝;方案二使用Littelfuse推出的P3203UCL SIDACtor保护晶闸管或P3206UCL SIDACtor保护晶闸管和04611.25表面贴装保险丝;方案三使用Littelfuse推出的P6002CBL保护晶闸管和600R150自恢复PTC,但由于产品性能的更新,P6002CBL保护晶闸管已淘汰。
方案一中使用的P1800SCL为DO-214AA SIDACtor固态保护器件用于保护调制解调器、传真机和其他电信用户端设备。而方案二中使用的P3203UCL和P3206UCL SIDACtor保护晶闸管使用六引脚表面贴装SOIC封装和Littelfuse的 "Y"专利(美国专利4,905,119)配置。 其额定浪涌电流可达500A。为表面贴装装置,可用于替代TO-220封装。
600R150自恢复PTC具有0.15 - 0.16安培保持电流,60伏直流工作电压,专为电信设备中经常发生的电源故障现象提供保护而设计。Littelfuse 04611.25 TeleLink®表面贴装型抗浪涌保险丝可在不使用串联电阻器的情况下,为各类电信设备提供过电流保护。
本解决方案专为符合Telcordia GR-1089室内标准要求而设计。P3206UCL采用独特的6引脚封装,是一个2端口解决方案。

【应用】5V电源下在PS/2接口避免受到ESD和过电流危害的电路保护方案
PS/2接口使用的数据信号的最大量值为5V,数据传输率为10,000 bps。可在电源总线和数据线路上使用Littelfuse推出的瞬态抑制二极管SP0503BAHTG防止其受到ESD影响。同时使用了PTC,以提供自恢复过电流保护。
【应用】自恢复型保险丝PTC 16R600G应用于车载加热杯电源部分,跳闸快速,安全无铅
本文主要是给车载加热杯电源部分选择合适的保险丝。鉴于加热杯属于消费电子类产品,选择熔断型保险丝会增加售后成本,所以推荐选择PTC自恢复型保险丝。从加热杯的主要功能可以得知,工作温度为60℃左右。littelfuse 16R600G较为合适。16R600G的工作电压为16V,也满足电源电路工作电压为12V的条件。且在正常工作状态下,电阻仅为0.028欧姆,对电路影响小。
【应用】SIDACtor保护晶闸管应用于开关电源初级防护电路,可以提高电路的防护等级
Littelfuse是一家专注于电子保护期间研发生产的企业。它生产的SIDACtor系列保护晶闸管可以应对过压工况下的电路防护。本文为读者介绍SIDACtor MC系列晶闸管推荐电路在开关电源初级保护中的应用,这款产品有着低容抗的特点,能够不影响后级防护电路宽频带的特点。

自恢复保险丝(PTC)的ITRIP电流的意义是什么?
Itrip可以叫做跳变电流,就是指电流超过该值时,电阻会出现大幅增加。其作为自恢复保险丝特有的重要参数,在设计选型时要格外重视。

如何为汽车电动车窗控制开关选择一款汽车级自恢复保险丝实现瞬时过载电流保护?
汽车电动车窗的控制开关接触瞬间会有很大的瞬时峰值电流,约300mA~500mA,持续时间约50ms以内,仅靠电阻无法做到快速响应保护,故设计电路需要再加一级保护,在电源线上串接一颗额定电压30VDC、保持电流Ihold为0.1A,跳闸电流Istrip为0.25A的littelfuse可恢复保险丝microASMD010F,实现瞬时过载电流保护,让控制系统实现高可靠性。

【技术】为实现过流电路保护,选择保险丝还是PTC更好?
使用传统保险丝或是使用最新研发的自恢复PTC都可以实现过流电路保护。 两者都是通过对电路中过量电流产生的发热现象做出反应从而实现保护功能。 保险丝是靠熔断来断开电流的,而PTC则是依赖从低阻态变为高阻态来限制电流的大小。 充分理解两种装置的性能差异会使您在选择最佳电路保护方案时做出更轻松的选择。
