Hall-Effect Current Sensor Delivers Multi-Axial Measurements to EVs

Texas Instruments (TI) launched the TMCS2100-Q1, a multi-axial coreless Hall-effect current sensor for HEV/EV traction inverters. The sensor measures magnetic fields in horizontal and vertical directions, reducing error and improving torque control. TI claims it is 20X more accurate than single-axis alternatives, with displacement error as low as 0.25%. The sensor is now available in production quantities.
