【选型】智能门锁触控芯片ESD防护推荐DFN1006小封装ESD保护二极管XE2F5VB,±30kV防护能力
随着科技的发展,智能门锁功能越来越完善,可以实时监控门的开关状态,提高安全性,而且有密码、指纹识别、二维码等方式开门,人们没有了出门忘带钥匙的烦恼。目前智能门锁多以密码的方式来开门,且基本利用的是触控芯片来输入密码。在人体接触中,极易因静电放电损伤敏感器件,所以通常在触控IC端加上ESD保护器件,其应用框图如下图所示:
图 应用框图
在智能门锁设计中,ESD保护器件选型因考量以下因素:
1.ESD防护等级至少满足IEC61000-4-2 ESD ±8kV Air/±15kV Contact,环境干燥时,人体接触极易产生静电放电;
2.小体积,智能门锁体积有限,应提高产品集成度;
3.低结电容Cj,此处属于低速数据线,结电容越低对数据传输的影响越小,此处属于低速数据线,30pF以内即可。
根据这些考量因素,笔者推荐矽航的高ESD防护等级小封装TVS管XE2F5VB,最大反向工作电压VRWM=5V,IEC61000-4-2高达±30kV(接触和空气放电)的ESD保护等级,并根据IEC61000-4-5承受高达8A(8/20μs)的峰值脉冲电流,DFN1006-2L小型封装,典型结电容14pF,其相关电气特性如下图二所示:
图二
XE2F5VB用于智能门锁触控IC端ESD防护有以下优势:
1.DFN1006-2L小型封装,典型封装尺寸1.0x0.6mm,触控IC至少有10个以上的端口,小型封装便于设计排版与提高产品集成度;
2.XE2F5VB具有IEC61000-4-2高达±30kV(接触和空气放电)的ESD保护等级,并根据IEC61000-4-5承受高达8A(8/20μs)的峰值脉冲电流,极大提高ESD防护能力;
3.矽航作为国产厂牌,交期有保障,价格有优势。

【应用】SIM卡ESD静电防护推荐TVS管XE6TLC5VU,结电容仅0.35pF,防护等级±30kV
由于SMI卡及数据线路易受到静电和浪涌损坏,因此需要外加ESD防护器件,要求ESD防护器件具有体积小、防护等级高的特性。本文推荐矽航的TVS管XE6TLC5VU,最大反向保持电压5V,击穿6V,最大漏电流1uA,ESD防护等级满足IEC61000-4-2标准±30kV(接触放电)/±30kV(空气放电)。
