Texas Instruments (TI) has introduced the TMCS2100-Q1, a multiaxial coreless Hall-effect current sensor for HEV and EV traction inverters. The device measures magnetic fields on horizontal and vertical axes and is specified for displacement error below 1% at 0.4 mm movement and as low as 0.25% at 0.1 mm, which supports tighter inverter current control under vibration and changing load conditions. The sensor architecture does not require busbar notches or holes, helping engineers reduce inverter size and simplify mechanical integration in 800V and other high-voltage EV platforms.
