BQ27Z561 1S-cell programmable battery manager Evaluation module


Order now


This evaluation module (EVM) is a complete evaluation system for the BQ27Z561 battery management system. The EVM includes a BQ27Z561 integrated circuit (IC) and all other components necessary to monitor and predict capacity and other parameters of a 1-series Li-ion or Li-polymer battery pack. The EVM also includes a link to a Windows based PC software, Battery Management Studio (bqStudio). The user can read the BQ27Z561 data registers, program the chipset for different pack configurations, log cycling data for further evaluation and evaluate the overall functionality of the solution under different charge and discharge conditions using I2C communication protocol through bqStudio software GUI.
