Overview

DESCRIPTION

· The CUR 3105 is a Hall-effect current transducer designed for precise current measurements.
· It features a ratiometric analog output proportional to the measured current and supply voltage.
· Key characteristics like magnetic field range, sensitivity, and output voltage are programmable and stored in internal EEPROM.
· The device includes temperature-compensated Hall plate, A/D and D/A converters, digital signal processing, and protection mechanisms.
· It supports individual programming of transducers connected in parallel to the same supply voltage.



FEATURES

· High-precision current measurement with 12-bit analog output.
· Low output voltage drifts over a wide temperature range.
· Programmable magnetic characteristics stored in non-volatile EEPROM with redundancy and lock function.
· Open-circuit detection, overvoltage, and undervoltage protection.
· Operates from -40°C to 170°C and 4.5V to 5.5V supply voltage, functional up to 8.5V.
· Robust against mechanical stress with EMC and ESD optimized design.



APPLICATIONS

· Suitable for industrial, white goods, and automotive applications.
· Ideal for environments requiring precise current measurement under varying temperatures and mechanical stresses.
