Hall-effect transducer measures from milliamps to hundreds of amps

Paul Boughton

Micronas is introducing the CUR 3105 Hall-effect transducer for applications such as battery monitoring, DC-DC converters, start-stop systems and 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 a flux concentrator using special conductor designs.
The CUR 3105 is able to measure currents with a bandwidth of up to 1kHz. The operating magnetic field range can be adjusted from +/-30 to +/-100mT. Various programmable parameters can be set to adapt the output characteristics which are stored in the highly reliable on-chip Eeprom.
To meet all the different assembly requirements, the CUR 3105 is available in a SOIC8 package and in a TO92UT package that can be soldered and welded. A wide temperature range from Tj -40 to 170 degrees C, open-circuit detection, and 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 EUR1.30 to 1.50 for quantities below 10,000 units.
Micronas will present the CUR3105 at the Sensor+Test trade fair in Nuremberg, Germany, (booth 12-302) from 18-20 May 2010, and at the Sensors Expo & Conference in Chicago, USA, (booth 715) from 7-9 June 2010.
