When tasked with a current sensing requirement, designers typically look first to using dedicated resistors designed for this task. Occasionally though there is the temptation to consider sensing ...
Current sensing devices are often desired in the power supply lines of various circuits, such as battery-powered computers, battery chargers or critical circuits requiring thermal forecasting. Figure ...
A voltage-to-frequency converter (VFC) can easily measure current flow and convert it to a digital signal understood by the timer/counter input of a microcomputer (µC) or microprocessor. It's a ...
In-circuit testers rely on bed-of-nails-type fixtures that give the tester access to every node (or net) of the printed circuit board (PCB). Using this access, the tester takes a divide-and-conquer ...
