Current sense amplifiers (CSAs) are specialized amplifiers that monitor current flow by measuring a voltage drop across a sensor element. You will find CSAs across multiple applications, such as ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...

It’s not easy being a current-sense resistor: so much is expected of this basic function of determining current flow by simple measurement of voltage across a known resistance, then applying Ohm’s Law ...

Can current-sensor ICs win out against the shunt resistor and other passive components? Check out some of the latest offerings on the market in this Products of the Week gallery. For any electronic ...
