Overview

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
