Recently, [Solder Hub] put together a brief video that demonstrates the basics of a Hall Effect sensor — in this case, one salvaged from an old CPU fan. Two LEDs, a 100 ohm resistor, and a 3.7 volt ...

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 ...

If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds ...

As systems extend and expand the exploitation of the latest power semiconductors (IGBTs, MCTs, etc.) that manifest the very relentless advance in power output limits, a prerequisite (and parallel) ...

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 ...

Designed for EVs and HEVs, these current sensors deliver accurate, isolated measurement for batteries, motors, and safety ...

What Is The Hall Effect? Discovered by Edwin Hall in 1879, the Hall effect is a phenomenon when voltage (potential difference) is generated across a current-carrying conductor when it is placed in a ...

Vineet Washington is a Tech/ Commerce Writer from Canada. He is a professional writer who is passionate about gaming and technology. With over 7 years of experience in content creation, 3 of which ...

Hall-effect magnetic field sensors measure ac and bidirectional dc with a minimum 800-V isolation. The ACS704 comes in a 1.7-mm-high SOIC8 package and is available in both 5 and 15-A versions.

Allegro MicroSystems Inc. has introduced the ACS704 family of Hall-effect magnetic field sensors in SOIC8 packaging, with the current path integrated into the package for better sensitivity and ...
