Integrated Load Switches versus Discrete MOSFETs
Alek Kaknevicius @ ti.com discuss about load switches and the advantages of intergrated switches over discrete ones. The most common approach to load switching solutions is to use a Power MOSFET surrounded by discrete resistors and capacitors; however, in most cases using a fully...Continue Reading
What Is Household Ground?
RimstarOrg published an interesting video on his Youtube channel to demonstrate why In north America you can find 3 holes in the electricity socket; which are hot, neutral and ground. The hot wire goes to a breaker-panel and then to electricity grid and finally to a transformer...Continue Reading
Simple circuit indicates health of lithium-ion batteries
Fritz Weld @ edn.com proposes a simple circuit to check li-ion battery health. He writes: Lithium-ion batteries are sensitive to bad treatment. Fire, explosions, and other hazardous condition may occur when you charge the cell below the margin that the manufacturer defines. Modern...Continue Reading
Simple circuit indicates a low battery
James Wood @ edn.com writes: The Design Idea in Figure 1 indicates a low-battery condition in an audio test instrument that is powered by four AA cells. As the instrument was otherwise an all-discrete design, this same approach seemed more in keeping with the spirit of the project...Continue Reading
