Hall-effect current transducer for contactless AC/DC measurement in automotive and industrial applications

(PresseBox) (Freiburg, ) The CUR 3105 from Micronas can be perfectly adapted to contactless current sensing applications by selecting the magnetic field range, by programming the required output characteristics and by choosing the suitable package.

Micronas (SIX Swiss Exchange: MASN), a leading manufacturer and supplier of innovative and applicationspecific sensor and IC system solutions for automotive electronics, presents its Halleffect transducer CUR 3105.

The CUR 3105 targets applications, such as battery monitoring e.g. in hybrid / electrical cars, DC-DC converters, startstopsystems or metering systems.

In combination with a flux concentrator the CUR 3105 is able to measure currents in the milliampere range. Currents in the hundred ampere range can be measured without flux concentrator using special conductor designs.

The CUR 3105 is able to measure currents with a bandwidth of up to 1 kHz. The operating magnetic field range can be adjusted from ±30 to ±100 mT. Various programmable parameters can be set to adapt the output characteristics which are stored in the highly reliable onchip EEPROM.

To meet all the different assembly requirements, the CUR 3105 is available in a SOIC8 package and in a solderable and weldable TO92UT package. A wide temperature range from Tj -40 to 170 °C, opencircuit detection, over- and undervoltage detection complete the characteristics of the CUR3105.

Engineering samples will be available in July 2010 and qualified samples in December 2010. The price for the CUR 3105 ranges from 1.30 to 1.50 Euros for quantities below 10k units.

Micronas will present the CUR3105 at the Sensor+Test trade fair in Nuremberg, Germany, (booth 12-302) from May 18 to 20, 2010, and at the Sensors Expo & Conference in Chicago, USA, (booth 715) from June 7 to 9, 2010.

About Sensor Solutions by Micronas

Micronas today offers the world's broadest range of Halleffect sensors. A Halleffect sensor detects the presence of a magnet without requiring actual physical contact. Thus, it can be used to sense movement and rotation without requiring contact with the moving object. Other parameters like pressure, force or torque can be sensed by noting the slight movements of a magnet caused by changes of the applied parameter.

While Halleffect sensors can be made from various materials, Micronas pioneered the market in CMOS Halleffect sensors and was the first to manufacture in CMOS technology. This technology allows integration of the Halleffect sensing element with standard electronic devices such as amplifiers, logic circuits, and volatile and nonvolatile memories.

Micronas' expertise in Hall sensors combines perfectly with its CMOS and mixedsignal design resources to create accurate, intelligent sensors for a broad range of applications. The everincreasing demand for energyefficient and highly reliable machines means that demand for these smart sensors will continue to grow.


Micronas (SIX Swiss Exchange: MASN), a semiconductor designer and manufacturer with worldwide operations, is a leading supplier of cuttingedge IC and sensor system solutions for automotive electronics. Micronas offers a variety of microcontrollers and Hall sensors for automotive and industrial applications, such as car dashboard, body control, as well as motor management and comfort functions.

Micronas serves all major automotive electronics customers worldwide, many of them in continuous partnerships seeking joint success.
