The ACS764 fully integrated Hall-effect current sensor IC is designed for applications that require digital current sensing and reporting through an I2C™ bus. Allegro factory programming of the offset ...

There’s many different ways of measuring current. If it’s DC, the easiest way is to use a shunt resistor and measure the voltage across it, and for AC you could use a current transformer. But the ...

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 ...

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 ...

Eddy current displacement sensors (ECDS) represent a mature, yet continuously evolving, non-contact measurement technology that utilises the principles of electromagnetic induction. When an ...

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 ...

Designed for EVs and HEVs, these current sensors deliver accurate, isolated measurement for batteries, motors, and safety ...

When taking measurements from analog sensors located at long distances, voltage drops and noise can affect precision of the readings. Therefore, a voltage-to-current (V/I) module is needed to transmit ...

In stock at authorised distributor Mouser Electronics is the ACS37100 10MHz TMR current sensor from Allegro MicroSystems.

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 ...
