【产品】JKPPTC系列自恢复保险丝,具有电流与温度双重调控特性,适合Type-C防护应用
近两年,在USB PD快充和大功率私有快充技术的普及下,Type-C充电接口的市场占有率呈现出几何级增长,并且成为了当下以及未来设备充电、数据传输的主要接口类型。根据资料显示,欧盟委员会已经开始立法程序,提议要求Type-C成为所有移动设备的标准充电端口,国家工信部也表示,将促进设备充电接口的统一。
Type-C接口介绍
Type-C接口全称为USB Type-C接口,是一种全新的USB接口形式,Type-C接口内部有4对TX/RX分线,2对USBD+/D-,一对SBU,2个CC,另外还有4个VBUS和4个地线,满针脚为24针,上下各12针。

由于采用对称针脚设计,配备Type-C接口的设备在充电时无需区分正反面,永远插不错。因此自从2014年USB-C规范发布后,许多新款的Android移动设备、笔记本电脑、台式机甚至是游戏机等智能设备都开始使用这种连接端口,大幅提升用户的充电体验。
Type-C接口的优势与缺点
Type-C接口作为一种全功能接口,不仅可以实现PD 3.1最高240W的电源传输功率,而且可以实现USB4最高40Gbps的数据传输带宽,还可以实现超高清视频、数字音频等多种数据类型传输,用一根Type-C数据线即可替代多根线材。
但Type-C数据线在日常使用中也存在一些比较明显的缺点:Type-C接口Pin脚的增多带来便利的同时,也带来风险,汗液或者是金属异物容易与Pin脚接触从而造成短路引发安全问题;使用Type-C数据线快充时,高功率带来的高温问题,不仅会影响产品本身,而且对内部电子元器件也有一定损伤。
针对上述问题,金瑞电子提供了一套方便、快捷、可靠的解决方案——JKPPTC系列自恢复保险丝产品,只要一个保险丝元件,串联于小USB的电源线上,即可达成具备出色性价比的保护效果。
自恢复保险丝(PPTC)介绍
PPTC全称为Polymer Positive Temperature Coefficient,是高分子聚合物正温度系数热敏电阻。
JKPPTC工作原理如上图所示,在正常温度下聚合物将导电物束缚在结晶状的结构中,形成一个低阻抗紧密排列的导电链,当大电流通过或外界环境温度升高时,会导致元件温度高于动作温度,聚合物融化膨胀使导电物形成无规律排列,元件阻抗迅速提高。
JKPPTC具有电流与温度双重调控的特性,可以有效针对TYPE-C接口易短路,温度高的特性。因此可排除过电流状况,达到保护电路及组件的目的。
JKPPTC产品如上图所示,只有当切断电源或故障修复后,JKPPTC才会自动恢复,不断电不会恢复,这一特性有效解决了温度降低而重复工作烧坏接口电路的潜在危险问题,同时又准确保护了接口电路及系统设备。
Type-C防护应用
目前,针对USB 3.0的过电流保护,业界已出现了新的PPTC组件,可确保设计符合USB 3.0版规范要求。例如,尽管USB 3.0降低了在电源端的电压要求,但新一代PPTC组件仍可确保PPTC的压降在电流全载时不超过0.1V,除可确保与USB 2.0装置的兼容性以外,也为主板上其它组件或线路保留了更大的设计余裕。
此外,新一代过电流保护组件皆能够在50℃以上高温时保持电流全载且不动作,避免PPTC组件因为温度的关系(thermal derating)而误动作,尤其是在桌上型计算机的后端USB端口。在上述应用场景中使用JKPPTC方案,不仅可以实现过温过流双重保护,而且可以有效节省成本。
PPTC与半导体开关对比
在USB 3.0的规范中,明确要求使用限电流组件作为电源端之保护,而PPTC组件及低电压半导体开关常被用来做此限电流的解决方式。大部分的时候,基于多种考量,工程师比较偏好使用PPTC组件来防止电路受到损害。因为可支配的电流量在USB 3.0中提高了,限电流的组件需要通过更多电流,但却同时要保持一定的压降。
在USB应用中PPTC与半导体开关的对比如上表所示。可以看到,PPTC在价格、故障电流和故障能量承受能力、静电敏感度、电能损耗等方面都更具优势。
金瑞电子JKPPTC系列产品选型如上表所示。采用0805封装可选JK-SMD0805-200L,JK-SMD0805-300L;采用1206封装可选JK-NSMD-400L,JK-NSMD-500L;采用1812封装可选JK-MSMD-700L。
Type-C接口凭借着完善的功能、强大的兼容性、正反盲插等优良特性,一经推出就受到了市场和消费者的热捧。不仅在智能手机、平板电脑、笔记本电脑等智能设备上实现全面覆盖,而且被广泛应用在真无线耳机、音箱、相机、剃须刀等设备中。
随着Type-C线材的普及,市场对Type-C线材的安全性要求也随之提高。金瑞电子此次推出的JKPPTC系列自恢复保险丝,具备高性价比、使用灵活、低阻低损耗、冲击耐受能力强等诸多优点,能够在主动保护失效的情况下,为线缆安全提供二级过温过流双重保护,保障消费者的使用安全。

竞沃自恢复保险丝关于TYPE-C应用的问题咨询
1:T45(TLC-NSML450)的工作原理:自恢复保险丝,平时工作在额定电流内,正常温度25度环境下,产品的发热与散热平衡,产品内阻不变化,产品正常工作。 如果温度过高的环境下,产品通过的电流导致自恢复保险丝产品内部的发热大于散热,产品内部温度到达居里点,产品内阻变大,从而保护。 2:在什么电流电压下保护:自恢复保险丝是过流产品,电压的变化并不会让自恢复保险丝有保护。 3:受外部加热的影响是否会保护:产品外部的热量对产品有影响,具体看产品的发热与散热是否能达到平衡,如果发热散热平衡,产品不保护,如果发热大于散热,产品就会保护。 4:跳闸后多久能恢复:产品保护后,需要断电一次才能恢复,恢复的时间一般几秒到几十秒就能恢复,具体看通过产品的电流是多大,如果产品还没有完全冷却,就开始通较大的电流,产品很容易进入保护,如果断电几十秒后,通较小的电流,产品正常工作是没有问题的
