【应用】微源半导体为电动牙刷提供解决方案,简化应用同时降低整体设计成本
随着居民的消费水平不断提升,口腔保健意识也逐步增强,我国的电动牙刷市场已迎来高速发展阶段。2015年我国电动牙刷渗透率为3%,2018年到达了5%。从其他国家例如美国电动牙刷普及率高达42%,日本电动牙刷普及率40%,西班牙的市场普及率占30%左右的比例来看,我国电动牙刷市场已由导入期进入成长期,即将迎来高速发展阶段。2017年我国电动牙刷的零售额同比增速高达92%,预计到2022年,我国电动牙刷市场规模将达到700亿元。同时电动牙刷也出现了智能化的趋势,结合了物联网,大数据等先进的计算机信息技术。
01 电动牙刷框图
电动牙刷的典型框图如下,USB输入或者无线充电提供电源给电池充电。目前很多充电器支持快充,其输出存在高电压的风险,所以电动牙刷的输入端需要增加过压保护器件以保证系统安全,可采用如微源半导体过压保护芯片LP5308。LP5308有5.8V过压保护阈值和36V高耐压,可有效保证系统安全(36V高耐压过压过流保护开关 - LP5308)。如果该牙刷支持无线充电,线圈的耦合可能导致接收端(Rx)出现高电压,通常的解决方式是在接收端增加LDO或BUCK稳压,否则可能出现高电压致使充电芯片因过压保护而停止充电。LP4078特别设计的宽工作电压,能确保在输入电压为21V以内时都可正常工作,在带无线充电功能的应用里,无线充电接收端可直接连到LP4078的输入,简化应用同时降低整体方案的成本(高性能40V耐压充电芯片 - LP4078)。可充电锂电池还需要一颗锂电池保护芯片来确保电池不会过充,过放,或过流,LPB1003能很好满足这一需求。
