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 ...

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 ...

Hall-effect sensors exploit the transverse voltage generated when a constant current passes through a semiconductor in the presence of a magnetic field. Integration of these devices in standard CMOS ...

Miri is a creative writer with a passion for gaming and animation. She started gaming way back in 1994 on the Super Nintendo and Sega Genesis and has been a console gamer ever since. She's currently a ...

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 ...

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 ...

A digital sensing approach promises cleaner current measurements, helping electric vehicle designers overcome electromagnetic ...

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) ...

Melexis is shipping a conventional-Hall current sensor featuring a sigma-delta digital output to improve signal integrity in electrically noisy environments. Supporting current sensing from 200 A to ...

These conditions can introduce disturbances along the signal path between the sensor and the MCU, particularly in systems where longer PCB traces or wiring are required. While analogue current sensing ...

Competitive gamers look for every advantage they can get, and that drive has spawned some of the zaniest gaming peripherals under the sun. There are plenty of hardware components that actually offer ...
