The Allegro ACS725LLCTR-40AB-T is an economical and precise current sensor IC designed for AC or DC current sensing in various systems. It utilizes a Hall effect sensor with differential sensing to reject common-mode fields, improving accuracy in noisy environments. The device features a primary conductor resistance of 1.2 mΩ for low power loss and a high inrush current withstand capability.
This sensor IC provides a ratiometric voltage output proportional to the current flowing through its integrated copper conduction path. It supports bidirectional current flow and offers a sensitivity of 33mV/A with an accuracy of ±1% and linearity of ±1.5%. The high bandwidth of 120 kHz allows for fast response times in control applications.
The ACS725LLCTR-40AB-T is housed in a small, low-profile 8-SOIC surface-mount package, making it ideal for space-constrained applications. The terminals of the conductive path are electrically isolated from the sensor leads, enabling high-side current-sense applications without the need for costly isolation techniques. Typical applications include motor control, load detection and management, switched-mode power supplies, and overcurrent fault protection.
