图 4 PWM 应用中应进行电流检测,即便在共模电压降至二极管电压降大小的负电压的回扫期间也要进行检测。
电流比较
在许多应用中,电流应与某个设定值相比较。通常说来,进行电流比较还需要电流分路监控器、比较器和参考电压。此外,理想的比较器输出应与大多数常见的逻辑电路很好地兼容。图 5 给出了电流比较的例子。在本例中,将电流与采用 TI INA200 系列电机控制器厂家电流分路监控器和比较器的简单单电压结点进行了比较。R1 和 R2 形成分压器,以根据 INA200 系列比较器的内置 0.6V 电压结点来设置电压结点。(INA200 系列的增益很有特点:INA200 的增益为 20,INA201 的增益为 50,INA202的增益为 100。)
