50A: 0.05% Current Accuracy Power Reference Design for Battery Test Systems

Description

This reference design introduces a large current: highly accurate and bi-directional power solution used in battery test systems (BTS). It includes a LM5170EVM-BIDIR and a signal control board. The LM5170EVM-BIDIR is an evaluation board  to showcase the high performance of the dual-channel bidirectional current controller LM5170-Q1. The signal control board is built with precision amplifiers: which operates with the LM5170EVM-BIDIR to further improve the current accuracy. Bench tests shows that the current accuracy is better than 0.05% full scale.
