Describes

This IC, developed by CMOS technology, is a programmable fast-response linear Hall effect sensor IC. It provides an analog output voltage proportional to the magnetic flux density based on the VREF pin voltage.

The IC has a built-in non-volatile memory and a 2-wire serial interface that allow flexible switching functions and trimming adjustments. Switching functions are available for the reference voltage operation mode, reference voltage output, output voltage polarity, frequency bandwidth, and thermal shutdown. High-precision trimming adjustments are available for sensitivity, sensitivity thermal drift, output offset voltage, and reference voltage output.

Because of its fast response, it is ideal for current sensor applications such as monitoring instantaneous overcurrent. 

Application

• Magnetic core current sensor

• Linear position detection

• Rotation detection
