【经验】BC817-16W-AU通用NPN三极管助力自行车追踪器开关电路设计方案优化
自行车,尤其是电动自行车已成为许多上班族和快递以及外卖送餐小哥重要的出行工具。近年来,随着外卖行业的快速增长,外卖送餐员规模快速扩大,对电动自行车的需求急速上升。此外,国家一直在倡导绿色出行,推动了电动自行车的发展。自行车的增多,自行车的网络化管理成为必须。笔者参与的一个项目就是为国内一知名品牌研发一款自行车追踪器,该追踪器包含实时定位,声光报警,超长待机等功能。从产品功能上看,该产品功能并不复杂,我们选择了集成蓝牙功能的超低功耗的MCU,外挂一个GPRS+GPS模块,声光报警部分根据客户的需求我们选择了大功率LED和蜂鸣器。由于考虑到功率和工作环境的要求。对于LED和蜂鸣器的驱动管,我们选择了世强代理的强茂电子的通用NPN三极管BC817-16W-AU,该三极管驱动电流高达500mA,电压45V,工作温度-55℃~150℃,封装为SOT-323小型封装,满足苛刻工作环境要求。
根据选型的蜂鸣器规格书中推荐的驱动电路如图一所示:
图一 蜂鸣器推荐驱动电路
我们设计了第一版原理图,基于强茂电子的通用NPN三极管BC817-16W-AU的蜂鸣器驱动电路,如图二所示。
图二 初版蜂鸣器驱动电路
由于该三极管参数余量较大,而且三极管驱动电路也比较简单,所以就直接打板做了工程样机。同时软件部分也出来了,所以就直接上车实测。但是令人懊恼的是,该蜂鸣器时常工作极不正常,经常在实际路测时意外发声或啸叫,发声也是时而怪异。而且在系统复位或电池出现异常时也会意外的发声。但是在实验室功能测试的时候,又是正常的。实际测试驱动波形也有没有什么问题。初步判断是环境有干扰,因为该追踪器安装的位置靠近电机的驱动模块,和客户沟通后,客户不愿意更改产品结构设计,只能我们自己想办法解决追踪器模块的干扰问题,提升电路的抗干扰能力。我们仔细研究和分析了电路,发现初始设计的三极管开关电路有一些缺陷,在图二的原始设计中,从三极管BC817-16W-AU(Q0101)的规格书中查到VBE最大为1.2V,VCE最大为0.7V,β为100-250,由于Q0101基极没有下拉电阻,虽然我们选择强茂电子的三极管基极导通的电压最高可达1.2V,但是在强干扰下,仍然会有高于1.2V的干扰信号使得Q0101误导通而产生意外啸叫,而且在MCU复位过程中,IO口的状态不定偶尔出现啸叫。所以需要提高Q0101的开关状态触发电压。另外实际调试中还发现蜂鸣器的发声有异响,没有达到规格书中的声压,仔细分析电路发现,蜂鸣器建议并联的1K电阻用于消除自身振荡,但是我们选择的是高声压蜂鸣器,工作电压范围较宽,初始设计选择3.3V供电,三极管Q0101的VCE为0.7V,在蜂鸣器上的电压约为2.6V,基本是工作电压的下限,加上1K电阻R519的分流,电流也达不到20mA。基本上没有发挥三极管BC817-16W-AU的优势。所以需要提升蜂鸣器的工作电压到5V。
经过仔细的计算和设计,最终优化该蜂鸣器的驱动电路如图三所示:
图三 优化后的蜂鸣器驱动电路
增加3.3K的下拉电阻R0107,在这里阐述一下优化后的蜂鸣器开启电压的计算。根据三极管工作在饱和开关状态,从三极管的规格书中看β为100-250,我们常温时选择β为200来计算,蜂鸣器的工作电流为20mA,可以认为IC为20mA,根据β=200,可以算出IB为0.1mA,根据VBE=1.2V,流过R0107的电流约为0.4mA,那么流过R0106的电流为0.4mA+0.1mA为0.5mA,这样蜂鸣器的开启IO电压等于R0106的上的电压0.5mA*3.3KΩ=1.6V再加上VBE的电压1.2V,可以达到2.8V左右。这样比原来的1.2V提升了很多,抗干扰能力大大加强。另外设计中也增加了防止蜂鸣器自身振荡滤波电路和保护二极管。从笔者的实际调试来看,一个简单的开关电路也需要注意细节的设计和推敲才能交付出可靠的产品。下面是交付的电路板图片,仅供参考,有什么问题希望大家一起交流!
