产品概述 返回TOP
The CXHA3149 CXHA3150 is a monolithic programmable Hall sensor IC, which provides a high speed analog output signal proportional to the external applied flux density. The sensor is ideally suitable for current sensing applications . Moreover, the sensor can be integrated in position sensing applications where fast response time is required. The transfer characteristics of the CXHA3149 CXHA3150 are fully programmable (offset, gain). The full analog chain features a fast response time and allows use of the sensor for applications where a very fast response time < 10 μsec is required. In the typical application the sensor is used in combination with a ring shaped soft ferromagnetic core. The Hall-IC is placed in a small air gap and the current conductor is passed through the inner part of the ferromagnetic ring. The ferromagnetic ring concentrates and amplifies the magnetic flux on the Hall-Sensor IC which generates an output voltage proportional to the current. Figure 2 shows a typical sensor application for a contact-less current measurement.
