BQ79600-Q1 Evaluation Module
The BQ79600-Q1 Evaluation Module user's guide describes the general features, theory of operation,
hardware setup, and use of the BQ79600EVM. Throughout this user's guide, the abbreviations EVM,
BQ79600EVM, and the term evaluation module are synonymous with the BQ79600-Q1 Evaluation
Module, unless otherwise noted. This EVM is an evaluation board for the BQ79600-Q1 device used as a
bridge IC to interface between a microcontroller and the TI battery monitoring ICs, for example BQ7961x-
Q1 family of devices. It translates between the daisy chain interface and SPI/UART interface.
