Product Summary

The ACS37002 is a fully integrated 400kHz Hall effect current sensor with extremely high accuracy, ideal for use in the control loop of demanding power conversion applications. Current flows through an integrated conductor coupled to the Hall sensor IC, generating a magnetic field. There is no physical connection between the current and the IC, providing high isolation. It is also sensed differentially by the two Hall plates, reducing external common-mode magnetic fields.

The sensor is factory trimmed to provide high accuracy over the full operating temperature range without customer programming. The sensor offers analog and reference outputs to ensure signal quality in noisy environments. It has fast overcurrent fault detection with user programmable thresholds. Four gain options are available with just two pin combinations without any additional components. This provides designers with flexibility and minimizes the overall BOM for systems requiring different current sensing ranges.
