Introduction：

The B1 series high-precision open-loop Hall current sensor is designed to meet the functional safety standards of ASIL-C/D. It is ready to replace existing high-precision sensors on the market at a lower price. This current sensor features a segmented calibration strategy, allowing it to measure both big currents (up to ±1500 A) and small currents (down to ±20 A) simultaneously. It provides an overall measurement accuracy of 0.5% across its entire range, with an offset level maintained within 100mA. The series can be tailored to meet specific preferences.
