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

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 ...

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 ...

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) ...

Two of the most widely used approaches for current sensing have shortcomings that limit their use in highly integrated power electronics applications. Hall-effect current sensors use a flux ...

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 ...

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 ...
