Most of the Allegro unidirectional current sensor ICs are trimmed such that the zero ampere output is at 0.1 × VCC. This application note documents a simple operational amplifier circuit which can be ...

Allegro MicroSystems, Inc. announces an open loop Hall-effect sensor IC with near closed loop performance (in accuracy and bandwidth). Allegro's ACS716 current sensor ICprovides an economical and ...

STMicroelectronics has introduced a precision digital current, voltage and power monitor with a an I3C bus interface. Called TSC1641, it has two 16bit ΣΔ converters at its inputs, allowing ...

Using a 25-µ? shunt, the SFP101 current, voltage, and temperature measurement IC from Sendyne typically achieves a current measurement accuracy to within ±0.05%, while operating over the automotive ...

Sensing current, especially in higher-voltage settings, is often a challenge. It’s generally more difficult than voltage sensing, as it is usually “invasive” and requires “breaking” into the ...

Electric motors that are either poorly maintained or which lack the proper electrical protection are the second greatest cause of electrical fires. So says the Factory Mutual Research Corp., a ...

Last week Belgian fabless chip company Melexis announced a unique inductive sensing IC that includes a tiny transformer, drive circuit and sense circuit, so Electronics Weekly decided to have a closer ...

Figure 1a shows a slotted optical switch. An LED is mounted in a plastic housing, facing a phototransistor, but separated by a gap. If something moves into the gap, it blocks the light path between ...
