解析电流采样电阻功率与阻值的关系
为什么电流采样电阻功率那么大、阻值却是很小？首先你要知道电流采样电阻是用来做什么的，用在哪个地方，如何用的，电流采样电阻一般是串联在电路当中，但是电压采样是并联的。采样电阻有插件的也有贴片的。因为采样电阻要真实反映出电流或者电压波动情况，因此要求精度要高，最好不能受温度影响，电流采样的话，阻值很大分压也就大。

就贴片电阻而言，像一般的贴片电阻功率都是根据封装就可以知道是多大的了，比如我们常见的0805封装功率一般是1/8W，1206是1/4W，1210是1/3W等。如果功率很大话，对于贴片电阻来说封装也会很大，比如45273封装，它的规格是11.6*6.85mm，达到这种电阻一般都是大功率电阻了，这种电阻适合作电流检测用，精度可以达到很高，材质一般都是合金组成，功率从1W到5W左右，但是它的阻值却是非常小，都是mΩ级别，一般都是1Ω左右，甚至有些达到1mΩ，可想而知精度要多高才可以，有1％、0.1％、0.01%等，要不然误差很大。
应用领域
因为电流采样电阻属于大中功率电阻，而且精度很高阻值又小，抗冲击能力大，温漂很低，受温度影响很小。因此被多用于各种电源产品、电力设备、充电桩、反馈电路、测量仪器等场合。我们都知道，电流检测时候一般是用电阻来检测，而且这个电阻阻值要很小，不像电压检测需要的电阻阻值可以大一点，通常采样电阻是串联在电路当中检测电流。

TMI8870的ISEN的PIN脚，加电阻，这个地方的电压能不能接到ADC进行采集，作为反馈？
7脚可以加SEN电阻，通过放大电路或者RC连接到ADC进行采样，这种采样方式不太准确，如果可行的话，建议用TMI8110，自带电流采样输出的，因为串联采样电阻的方式，很多时候电流不走采样电阻，或者电流方向会反向
