Monolithic Power Systems (MPS) MCQ1806 Automotive Hall-Effect Current Sensors
Monolithic Power Systems (MPS) MCQ1806 Automotive Hall-Effect Current Sensors are designed for AC and DC sensing. The Monolithic Power Systems (MPS) MCQ1806 sensors' differential Hall array cancels stray magnetic fields, while a low-resistance primary conductor directs current near the IC. The current generates a magnetic field, detected at two points by Hall-effect transducers. The difference in the magnetic field is converted into a voltage proportional to the current. A spinning current technique ensures a low and stable offset.The galvanic isolation between the pins of the primary conductive path and the sensor leads allows the MCQ1806 to replace optoisolators and other isolation devices.
The MCQ1806 requires a minimal number of readily available, standard external components. The device's small SOIC-8 footprint saves board area and is well-suited for space-constrained applications.
