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 ...

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 ...

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 ...

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 ...

A Hall-effect sensor is a transducer that converts a magnetic field directly into a usable electrical voltage. It enables engineers to perform non-contact measurement of shaft rotation, detect the ...

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 ...

LEM has introduced a unique current sensor for electric-vehicle (EV) battery management. Dubbed the Hybrid Supervising Unit (HSU), the device is the first on the market to integrate both shunt and ...

The ongoing computerization of vehicle systems is leading to additional electronic control units (ECUs) and sensors to ensure effective control. So, Hall effect sensors are widely adopted for their ...

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 ...

As previously mentioned, the feedback sensors include position sensors to track the rotor’s location, current sensors to measure the motor phase currents, voltage sensors to monitor the DC bus voltage ...
