负载电源监视器提高高边电流测量

资料介绍
测放大器, MAX4211显示,可以很容易地测量负载消耗的功率。一个乘法器输入连接到负载电压,负载电流是内部模拟,成比例的电压由内部的电流检测放大器。乘法器的输出( VLIL )是成正比的电压,负载功率。

APPLICATION NOTE 4507
Load-Power Monitor Improves High-Side Current Measurements
By:Maurizio Gavardoni


Abstract:Combining a high-side current-sense amplifier with an analog voltage multiplier, MAX4211 shown can easily measure
the power dissipated in a load. One multiplier input connects to the load voltage, and the other to an internal analog of the load
current―that is, a proportional voltage produced by the internal current-sense amplifier. The multiplier output (VL IL ) is then a
voltage proportional to load power.
