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.
Features
- High precision calibration control achieving 0.02% full scale current control accuracy and 0.01% full scale voltage control accuracy
- Supports from 0.5-A to 100-A charge and discharge
- Input voltage (bus) from 8 V - 16 V and output load (battery) from 0 V - 4.2 V (5 V max)
- Two LM5170 multiphase bidirectional buck, boost integrated controllers and drivers for charging and discharging
