Automotive Certified Ultra-Small Current Sensor MCQ1823

Hall-Effect Current Sensor IC by MPS

MCQ1823 from MPS is an automotive-grade, linear Hall-effect current sensor IC for suitable both AC and DC current sensing. A differential Hall measurement topology cancels out homogeneous or gradient stray magnetic fields.

Usage of the Spinning Current Technique

The primary conductor’s low resistance (0.6mΩ) allows large currents to flow within close proximity to the integrated circuit that contains high-accuracy Hall sensors. This current generates a magnetic field, which is sensed at two different points by the integrated Hall transducers. The magnetic field difference between these two points is then converted into a voltage that is proportional to the applied current. A spinning current technique is used for a low, stable offset.

The MCQ1823 integrates fast over-current detection (OCD), which makes it simple to monitor system over-current (OC) events. Different versions from +/-5A to +/-50A with 3.3V or 5V supply are available. The MCQ1823’s small footprint reduces board area and makes this device well-suited for space-constrained applications. The MCQ1823 is available in an ultra-small TQFN-12 (3x3mm) package, and is AEC-Q100 qualified.
