【选型】车规电流电压采样芯片SI8931D-IS4 pin to pin兼容ACPL-C87AT做电路采样设计
涉及到汽车相关的产品,比如电驱,车载DC-DC,OBC等运用对元器件都需要满足车规的要求,针对电流或者电压采样,目前有开环或闭环霍尔,分流器加运放,采样电阻加采样芯片等方案。从精度及对AEC-Q100的要求等综合考虑,采样电阻加采样芯片的方式设计最好。针对目前用到的车规电压或电流采样芯片ACPL-C87AT,SILICON LABS推出了SI8931D-IS4完全pin to pin兼容的ACPL-C87AT,SI8931D-IS4具有增益为1,±0.04%的非线性度,典型值0.1%的增益误差,工作温度范围支持-40℃-125℃,满足AEC-Q100认证,在兼容ACPL-C87AT的同时,性价比更优。
SI8931D-IS4在设计上可以与ACPL-C87AT完全实现兼容,都是输入采电阻上的电压信号,以单端的形式,差分的方式输出,典型运用如图1所示,需要注意的是SI8931D-IS4的输入侧第3脚为NC,ACPL-C87AT的输入侧第3脚为SHTDN,实际的设计时,SHTDN是接地的,所以这点设计两者电路是可以兼容。
图1 SI8931D-IS4设计典型运用
另外作为设计者来讲希望将两者参数做个对比,图2为SI8931D-IS4与ACPL-C87AT的性能参数对比表:
图2 SI8931D-IS4与ACPL-C87AT的性能参数对比表
通过图2可以看到SI8931D-IS4在一些性能指标上是优于ACPL-C87AT,从可靠性及性价比考虑,SI8931D-IS4非常的适合对有车规要求的电流或电压采样芯片运用。

AMC1200为什么常用电路推荐
AMC1200属于隔离芯的电压及电流采样芯片,可以参考Silicon Labs的SI8920的典型运用设计,属于差分式输入,输出,资料链接:https://www.sekorm.com/doc/617439.html;
【应用】PFC电流检测的低成本方案:带隔离的电流采样芯片SI8920,高精度、小体积
目前的PFC设计通常需要检测环路的电压及电流,使效率达到最高化,对于PFC的电流检测方法通常会涉及到隔离问题,用带隔离的电流检测芯片会更好,Silicon Labs推出的SI8920具有高精度,小体积,低成本的优势非常适合PFC的电流检测芯片。
【IC】先积新推车规级高精度运放LTC726Q/LTC728Q,失调电压为±0.65mV(Max),带宽增益积11MHz
专注于高性能模拟密集型芯片和先进的传感器解决方案的高新技术企业先积集成推出车规级精密运放。LTC726Q为双运放,LTC728Q四运放,适合于单电源供电+1.8V~+5.5V工作,耐压可达10V。11M带宽可用于电机及电源系统电流采样。
【应用】采用车规级SiC功率器件设计的高效6.6KW OBC方案
传统6.6 KW OBC采用Si功率器件来做设计,存在开关频率低,反向恢复时间慢及开关损耗大等问题,效率偏低。为解决上述问题,在主回路电源设计选用车规级SiC MOS管及SiC 二极管,能支持更高开关频率,实现更好开关特性及降低损耗,另外搭配双路的车规驱动芯片,高精度的车规电压采样芯片,高通信速率车规容隔离芯片,可以实现系统效率提升约1%,使6.6KW OBC更高效。
