Current sensing is on a trajectory to intersect with the global high-voltage trend of robust, high-performing systems. Discover the tradeoffs between isolated shunt-based, closed-loop Hall-effect, and ...

The A138x family of analog position sensors from Allegro MicroSystems is fully programmable so that users can optimize the devices for the completed assembly. Enlarging its portfolio of ...

Measuring a magnetic field can be very easy with some pretty low tech, or it can be very high tech. It just depends on what kind of measurement you need and how much effort you want to expend. The ...

The A1301 and A1302 ratiometric, linear Hall-effect sensors in a SOT23 package are rated for operation to 150°C. Output voltage is 50% that of supply voltage and output sensitivity is 1.3 and 2.5 mV/G ...

Diodes Incorporated has launched its first automotive-compliant 3D linear Hall-effect sensor. The AH4930Q detects the magnetic field in the X, Y, and Z directions, enabling high-precision contactless ...

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 ...

Melexis has brought out a linear Hall-effect sensor that draws less than 5 µA at 100 Hz and integrates digital filters for enhanced performance. Its flexible architecture is available in multiple ...

If you read about Hall effect sensors — the usual way to detect and measure magnetic fields these days — it sounds deceptively simple. There’s a metal plate with current flowing across it in one ...
