Battery tester reference design for multi-phase high-precision 0.5 to 100 A battery formation
Description
This reference design provides a multi-phase solution for a wide range of current battery test applications. Leveraging the dual phase buck/boost controller LM5170's daisy chain configuration gives the design the ability to achieve 100A charging/discharging rates. Utilizing high accuracy constant current (CC) and constant voltage (CV) calibration loops: TIDA-01041 can achieve up to 0.01% voltage control accuracy. All key design theories are described guiding users through the part selection process and optimization. Finally: schematic: board layout: hardware testing: and results are also presented.
