WebHow to: Choose Between High-side and Low-side Switching Elektor Magazine The principles of operation of high-side and low-side load switching are easy to grasp, but when do you prefer one method to the other? The principles of operation of high-side and low-side load switching are easy to grasp, but when do you prefer one method to the other? WebActive Low. Active Low means that the default signal is at HIGH level. As long as the pin is not pulled LOW, the pin does not become active. Let’s look at this example in Figure 1: Imagine you have an IC with an enable pin. From the overline and the datasheet you find out that this pin is active low pin. This means that as long as this pin is ...
