It is specifically designed to be used for both AC and DC current sensing in a wide range of industrial, commercial, and communication systems. This compact device provides outstanding performance while also saving valuable board space and reducing costs. This guide provides a comprehensive overview of the ACS723KMATR-20AB-T, including its features, applications, and benefits. It focuses on its suitability for motor control, load detection and management, switched-mode power supplies, and overcurrent fault protection.
Understanding the ACS723KMATR-20AB-T
The ACS723KMATR-20AB-T is equipped with a linear Hall sensor circuit that is highly accurate and has a low offset. The design of this product is unique because it includes a copper conduction path that is situated near the surface of the die. When an electric current passes through the copper conduction path, it generates a magnetic field. This magnetic field is then detected by the integrated Hall IC. The Hall IC is responsible for converting the magnetic field into a voltage that is directly proportional to it. This allows for accurate and precise measurements of the current. The Hall transducer’s close proximity to the magnetic field of the device ensures optimal accuracy.
