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.

Summary of Contents for Texas Instruments BQ79600-Q1

  • Page 1: Table Of Contents

    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.

  • Page 2: General Description

    State of Charge (SOC) and State of Health (SOH) estimation. The EVM is equipped with an UART/SPI interface 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 3: Theory Of Operation

    The typical BMS system consists of a Battery Management Unit (BMU) and one or more stacked Cell Monitoring Units (CMU). The BMU should be isolated from the CMU using transformers to keep the high voltage of the stacked battery modules isolated from the BQ79600-Q1 bridge device and the microcontroller.

    7. The host can then decide to repeat the process (back to step 4) or return later. When using the BQ79616-Q1 in a ring architecture, the host can enable the sniffer detector on the BQ79600-Q1 and the FAULT tones in the BQ97616-Q1, then send the stacked devices to SLEEP and the bridge and itself to shutdown.

    Ensure that J6 jumper on BQ79600EVM is connected in position 1-2 (default) to connect 3.3-V supply from the LaunchPad to BQ79600-Q1 VIO pin. TMS5701224 microcontroller does not support 5-V option, therefore avoid powering VIO pin with 5 V when connecting to the LaunchPad.

    The software provides a command API and drivers that are capable of implementing the examples provided in the BQ79600-Q1 Software Design Reference document. The example code only provides a control interface to the BQ79600-Q1 and BQ79616-Q1 and does not provide any other communications interface to the outside world. The customer is expected to develop their own communication implementation.
