A flexible Multi-Hall-Array allows linear or differential magnetic-field sensing for contactless and precise current sensing up to >=2000 A. CUR 4000 can be used for different module concepts like core-based or coreless. In the linear modes of CUR 4000, a configurable array of Hall elements enables highly accurate measurements for core-based stray-field robust sensor-module designs. The differential mode enables small coreless and stray-field robust system designs without shields. Read-out of the complete Hall array provides an output-offset temperature-drift below ±0.05 percent full scale. Furthermore, the sensor delivers a hysteresis-free output signal. A non-linearity error of ±0.2 percent and a noise performance of ±0.005 percent full scale allows precise current measurements with a signal bandwidth of up to 8 kHz. Current sensing modules equipped with the CUR 4000 can be programmed directly in-circuit by a microcontroller via SPI interface. CUR 4000 is defined as ASIL-B ready SEooC (Safety Element out of Context) according to ISO 26262. Major characteristics like gain and offset, etc. can be adjusted to the magnetic circuitry by programming the non-volatile memory. The device is qualified according to AEC-Q100-Rev-H and is designed for automotive applications with operation in an ambient temperature range (TA) of –40 °C up to +150 °C. CUR 4000 is available in a small eight-pin SOIC8 SMD package. Block diagram – system architecture All products of this family CUR 4000 Package: SOIC8 Ordering Code: CUR4000 Interface : SPI Temp.
