MCS1826 Linear Hall Effect Current Sensor ICs

The MCS1826 from Monolithic Power Systems is a linear Hall effect current sensor IC designed for both AC and DC current measurement. It features a differential Hall array, which helps reject uniform and gradient stray magnetic fields for improved signal integrity.

With a low-resistance primary conductor (0.6 mΩ), the MCS1826 enables high-current operation close to the integrated Hall sensor IC. The current flowing through this conductor produces a magnetic field that is sensed at two separate points by precision Hall transducers. The difference in the magnetic field between these points is converted into a voltage signal directly proportional to the sensed current. A spinning current technique is employed to achieve a low and stable offset.

For enhanced system protection, the MCS1826 includes integrated fast over-current detection (OCD), allowing for straightforward monitoring of over-current (OC) conditions.

Its compact design minimizes the PCB footprint, making it an excellent choice for applications with limited board space. The MCS1826 is packaged in a tiny 3 mm x 3 mm TQFN-12 form factor.
