Most of the Allegro unidirectional current sensor ICs are trimmed such that the zero ampere output is at 0.1 × VCC. This application note documents a simple operational amplifier circuit which can be ...

Littelfuse has introduced a new range of automotive-qualified current sensors aimed at improving the performance, efficiency, ...

As power electronics switching techniques advance, there is an increased need to accurately measure current for feedback control and system monitoring. There are several methods to achieve this, and ...

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 sensor that I somehow missed, despite it being a popular building block in module form is the WCS1800 current sensor from Winson of Taiwan. It is part of a large family of current sensors from the ...

Allegro MicroSystems today announced three ICs: two analogue current sensors and a motor driver for fans. The first current sensor, ACS37630, is designed to be sat on top of a bus bar and partly ...

Designed specifically for high-voltage sensing, a new generation of optically isolated amplifiers make monitoring and system protection circuits more accurate and easier to design. These iso-amps can ...

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 ...

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 ...
