Description

This reference design shows how to detect current from the mA-to-KA range using a busbar-type shunt resistor. The increasing demand of high-capacity batteries in electric vehicles (EVs) and hybrid electric vehicles (HEVs) drives the requirement for larger current spans and highly-accurate current sensors. Obtaining a good accuracy over three decades (mA to A, 1 A to 100 A, and 100 A to 1000 A) is quite challenging due to large amounts of noise in the system. This design solves this problem by using a high-resolution analog-to-digital converter (ADC) and high-accuracy current shunt monitors from TI.
