A ±36-A Integrated Current-Sensing System with a 0.3% Gain Error and a 400-μA Offset From-55 °c to +85 °c

This paper presents an integrated shunt-based current-sensing system (CSS) capable of handling ±36-A currents, the highest ever reported. It also achieves a 0.3% gain error and a 400-μA offset, which is significantly better than the state-of-the-art systems. The heart of the system is a robust 260-μ Ω shunt resistor made from the lead frame...
