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 ...

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 ...

Six automotive current sensors designed to enhance electric and hybrid vehicle performance, efficiency, and functional safety ...

Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...

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

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 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 ...

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 ...

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 ...
