Additional Details:

The ACS764XLFTR-16AU-T utilizes Hall-effect technology to precisely measure the magnetic field generated by the current flowing through the integrated conductor. This allows for non-intrusive current sensing, eliminating the need for external sense resistors and reducing power losses. The device's SOIC-16 wide body package provides improved creepage and clearance compared to standard SOIC packages, enhancing safety and reliability in high-voltage applications.

The device operates from a single 5 V supply and provides a ratiometric output, meaning the output voltage is proportional to the supply voltage, which reduces the impact of supply voltage variations on accuracy. Its wide bandwidth enables accurate measurement of high-frequency currents, making it suitable for applications such as switched-mode power supplies and motor control. The ACS764XLFTR-16AU-T is designed for demanding applications and incorporates features to ensure robust performance and reliable operation.
