Description

The BQ27Z846 evaluation module (EVM) is a system-level board created to enable users to evaluate the functionalities of the BQ27Z846 fuel gauge within a system. The BQ27Z846 EVM is suitable for applications in which the battery pack is 1-S cell, meaning one series cell. The EVM includes a BQ27Z846 battery fuel gauge, a high-side and low-side current sense resistor, integrated high-side protections, an ENAB wake button, a charger wake button, and other header options to allow for some modifications to meet the intended application.
