style="font-size:14px;">电流采样部分的是INA199B1DCKR电流感应放大器,(也称为电流传感放大器)常用于过流保护、针对系统优化的精密电流测量或闭环反馈电路。该系列器件可在独立于电源电压的–0.3V至 26V共模电压下感应分流电阻器上的电压降。共有三种固定增益可供选择:<strong>50V/V</strong>、100V/V和 200V/V。该系列器件采用零漂移架构,偏移较低,因此在进行电流感测时能够将分流电阻器两端的最大压降保持在最低10mV的满量程。参数如下:</span></p> <ul><li style="list-style-type:none;"> <ul><li style="list-style-type:none;"> <ul><li style="list-style-type:none;"> <ul><li><span style="font-size:14px;">共模范围:–0.3V至26V</span></li> <li><span style="font-size:14px;">偏移电压:±150μV(最大值)</span></li> <li><span style="font-size:14px;">支持 10mV 满量程分流压降</span></li> <li><span style="font-size:14px;">静态电流:100μA(最大值)</span></li> </ul></li> </ul></li> </ul></li> </ul><h3 style="padding-left:40px;"><span style="font-size:14px;">采样电阻选择</span></h3> <p style="padding-left:40px;"><span style="font-size:14px;">在电流路径中以串联的方式插入一个低阻值的检测电阻会形成一个小的电压降,该压降可被放大从而被当作一个正比于电流的信号。然而,根据具体应用环境和检测电阻的位置,这种技术将对检测放大器造成不同的挑战。一般采样电阻的电阻值在1欧姆以下,属于毫欧级无感应电阻,但有些电阻,有采样电压等要求,必须选择大电阻值电阻,但电阻基数大,误差大。在这种情况下,需要选择高精度的无感应电阻(可达到0.01%精度,即万分之一精度),使取样数据非常可靠。贴片的超低电阻值电阻(0.0005欧姆、2毫欧、3毫欧、<strong>10毫欧</strong>等)、贴片合金电阻、大功率电阻(20W、30W、35W、50W、100W)等产品,温度系数为正负5PPM。</span></p> <h4 style="padding-left:40px;"><span style="font-size:14px;">采样方式</span></h4> <ul><li style="list-style-type:none;"> <ul><li style="list-style-type:none;"> <ul><li style="list-style-type:none;"> <ul><li><span style="font-size:14px;">此采样使用的是<strong>低边采样</strong>的方式,也就是采样电阻接在GND的回路上,此设计可以在差分信号送入运放的时候,运算完整的差分、跟随、放大、输出。如果使用高边采样,也就是采样电阻放置在电源和负载之间的高位,虽然这种放置方式不仅消除了低边检测方案中产生的地线干扰,还能检测到电池到系统地的意外短路,但是<strong>高边检测</strong>要求检测放大器处理接近电源电压的共模电压。这种共模电压值范围很宽,从监视处理器内核电压要求的电平(约1V)到在工业、汽车和电信应用常见的数百伏电压不等。应用案例包括典型笔记本电脑的电池电压(17到20V),汽车应用中的12V、24V或48V电池,48V电信应用,高压电机控制应用,用于雪崩二极管和PIN二极管的电流检测以及高压LED背光灯等。因此,高边电流检测的一个重要优势,那就是检测放大器具备处理较大共模电压的能力。</span><br><span style="font-size:14px;">所以,采样电阻加运放的电流采样方法,最好是在低端进行。虽然,低端采样,由于共地干扰的原因会影响信号的纹波情况。但是相对高端来说,<strong>方案简单易行,成本低,可靠度高。</strong></span></li> <li><span
