The ACS712ELCTR-20A-T is a Hall effect-based linear current sensor IC from Allegro Microsystems, designed for sensing currents up to ±20A. It outputs an analog voltage linearly proportional to the sensed current and is available in a surface-mount SOIC-8 package. Key features include high sensitivity, low offset, and a compact design, making it suitable for applications such as battery chargers, power management systems, over-current protection, motor control, robotics, and automotive systems. Its non-intrusive sensing capability ensures accurate current measurement without modifying the existing electrical system.
