Additional Details:

The ACS706ELC-20A is factory-trimmed for accuracy. It provides an analog output voltage proportional to the sensed current. The device operates from a single 4.5 V to 5.5 V supply. The current to be sensed flows through an internal conductor, and the Hall effect sensor measures the magnetic field generated by this current. The integrated shield minimizes the effects of external magnetic fields and improves the accuracy of the measurement. The device is calibrated to measure currents up to ±20 A. The output voltage is ratiometric, meaning it scales proportionally with the supply voltage. This current sensor is commonly used in applications requiring accurate and reliable current monitoring, such as motor control, power supplies, and automotive systems. The device offers excellent linearity and temperature stability over its operating range. It includes integrated fault detection features for overcurrent protection. It is available in a RoHS-compliant package, ensuring environmental compliance.
