Allegro MicroSystems, LLC rolled out two new current sensor ICs that are economical and precise solutions for AC or DC current sensing. These devices are ideal for use in industrial, commercial, and communication systems that require very high voltage isolation. These devices are not for use in automotive applications. Both the ACS724KMA (5 V) and the ACS725KMA (3.3 V) are available in a very small package that is ideal for space-constrained applications while saving cost due to reduced board area. They are packaged in a high-isolation SOIC16 wide body surface mount package that provides reinforced isolation. The differential sensing technology provides immunity to interfering common mode magnetic fields from adjacent current traces or motors. Typical applications include motor control, load detection and management, switched-mode power supplies, and overcurrent fault protection.
