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 and BQ79606A-Q1). The device
translates between the daisy chain interface and SPI/UART interface.

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 and BQ79606A-Q1).

Page 3: General Description
State of Charge (SOC) and State of Health (SOH) estimation. The EVM is equipped with an UART/SPI to enable a host device to communicate to the BQ79600-Q1 device and an isolated differential daisy chain interface to enable communication to a stack of battery monitoring ICs. The BQ79600EVM acts as a communication bridge between the host and the battery modules. -
Page 4: Theory Of Operation
Power management IC (PMIC) • BQ79600-Q1 isolated communication bridge device - in this case a BQ79600EVM The BQ79600 device can be powered from the 12-V battery directly or from the PMIC. When powered from the 12-V battery, the reverse wake-up function on the BQ79600 can be used in a ring architecture to wake up the PMIC and the microcontroller with an unmasked fault is detected. -
Page 5: Compatibility With Battery Monitoring Devices
The BQ79600-Q1 is fully compatible with the BQ7961x-Q1 family, supporting automatic host wake up through the INH pin when an unmasked fault is detected in the high voltage battery pack. The BQ79600-Q1 is also compatible with BQ79606A-Q1 devices without the fault interface. -
