STEVAL-ISQ013V1演示板实现了低侧电流检测，其中包括在将所述负载和电路的接地和由此产生的压降，是利用TS507运算放大器的放大之间的检测电阻。Current sensing is very useful for protecting applications. The STEVAL-ISQ013V1 demonstration board implements a low-side current sensing which consists in placing a sense resistor between the load and the circuit ground and the resulting voltage drop is amplified using a TS507 op amp.The common mode voltage is close to ground, whatever the voltage of the power source, so the current sense voltage can be amplified by this low voltage op amp without any restrictions.The circuit offers very stable electrical characteristics over the entire supply voltage range and is particularly intended for automotive and industrial applications.
