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 ...

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

Allegro MicroSystems’ two high-performance, low-noise 2100-Vrms isolation current sensors, the ACS712 (bidirectional) and ACS713 (unidirectional), provide lower noise and higher accuracy than previous ...

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 ...

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 ...

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 ...

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 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) ...
