The Allegro ACS724KMATR-20AB-T is an economical and precise Hall effect current sensor IC suitable for AC or DC current sensing in industrial, commercial, and communication systems. Its compact 16-SOIC package is ideal for space-constrained applications.
This sensor IC features a precise, low-offset, linear Hall sensor circuit with a low-resistance copper conduction path (0.85 mΩ typical) for minimal power loss. It provides a ratiometric voltage output proportional to the current, with a sensitivity of 100mV/A and an accuracy of ±1%. The device operates from a single 4.5V to 5.5V supply and has a wide operating temperature range of -40°C to 125°C.
Designed for high-side current sensing without requiring costly isolation techniques, the ACS724KMATR-20AB-T utilizes differential Hall sensing to reject common-mode fields, enhancing accuracy in noisy environments. It supports bidirectional current measurement up to 20A with a response time of 4µs and a bandwidth up to 120kHz.
Typical applications include motor control, load detection and management, switched-mode power supplies, and overcurrent fault protection.
