Introduction

The CHI612 is a customer programmable, low noise high accuracy linear Hall effect- based sensor IC. It is packaged in subminiature package to allow for easy integration with a magnetic core to create a highly accurate current sensing module. The programmable nature of the CHI612 enables it to account for manufacturing tolerances in the final current sensing module assembly.

These ratiometric Hall effect sensor ICs provide a voltage output that is proportional to the applied magnetic field. The quiescent voltage output is user adjustable around 50% of the supply voltage and the output sensitivity is programmable within a range of 1mV / G to 24mV / G

This temperature- stable device is available in a through- hole single in- line package (TO- 92s). The accuracy of the device is enhanced via programmability on the OUT pin for end of- line optimization without the added complexity and cost of a fully programmable device. The device using EERPOM to optimize device sensitivity and the quiescent output voltage (QVO) (output with no magnetic field) for a given application or circuit. The CHI612 also allow for optimized performance over temperature through programming the temperature coefficient for both Sensitivity and QVO at end of line test.

The features of this linear device makes it ideal for use in industrial applications requiring high accuracy and are guaranteed over a wide temperature range, - 40℃ to +150℃
