BMS300 Automotive Current Sensor Transducer

BMS300 fluxgate transducer is made of an excitation magnetic ring and a control circuit. Under normal
conditions, the control circuit generates a fixed excitation current frequency to alternately place the magnetic
core at the maximum saturation point. When the measured current flows, the primary current is measured by
detecting the symmetry of the saturation point.

The BMS series is suitable for battery monitoring systems that require high accuracy and low offset.
It can realize the isolation measurement between the primary current (high voltage) and the secondary
current (12V system).
