Allegro MicroSystems' two high-performance, low-noise 2100-Vrms isolation current sensors, the ACS712 and ACS713, provide lower noise and higher accuracy than previous generation current sensors.

The technique is called high-side current sensing. However, measurements at that location are fraught with problems. Of primary concern is that the measurement is at main line voltage, a problem if ...

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 ...

Two new tunnel magnetoresistance (TMR) current sensors streamlined for low noise and high power density designs aim to facilitate precise current measurements for artificial intelligence (AI), data ...

Motor control circuits in appliances including refrigerators, washing machines and air conditioners, need to operate more efficiently, reliably and safely while meeting cost requirements. With energy ...
