Monolithic Power Systems (MPS) MCQ1805 Hall-Effect Current Sensors

Introduction

The Monolithic Power Systems (MPS) MCQ1805 Hall-Effect Current Sensors are advanced automotive-grade sensors designed for precise AC or DC current sensing. With their compact design and high performance, these sensors are ideal for a variety of applications, particularly in automotive systems and motor controls.

Part Description

The MCQ1805 sensors utilize a differential Hall array that effectively cancels out stray magnetic fields, ensuring accurate current measurements. They are engineered to provide fast Over-Current Detection (OCD), which is crucial for monitoring faults in various systems. The sensors feature a low-resistance primary conductor that directs current near the integrated circuit (IC), generating a magnetic field that is detected by Hall-effect transducers. This difference in magnetic fields is converted into a voltage that is proportional to the current being measured. With a minimum isolation voltage of 3kVRMS and a maximum working voltage of 580VRMS, the MCQ1805 sensors are designed for reliability and safety in demanding environments. They are available in a compact SOIC-8 package, making them suitable for space-constrained applications.
