1 General Description

TI's BQ79600EVM Battery Management System (BMS) 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 BQ79600EVM can be powered through a PMIC device or directly through a 12-V battery. The device has an Auto Host Wake-up function that can be utilized with the BQ7961x-Q1 family to automatically wake up the host when an unmasked fault is detected in the battery monitoring ICs when using ring architecture. See the BQ79600-Q1 data sheet for more details.

The BQ79600EVM enables communication between a controller and one or more battery modules to perform 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.

The BQ79600EVM is controlled using a PC-hosted GUI. Communication between the PC and the BQ79600EVMs is through an USB2ANY UART interface or an USB2ANY SPI. Communication between the BQ79600EVM and all BQ79616EVMs in the stack is via the isolated, daisy-chain differential communication bus. The GUI allows configuration of the BQ79600EVMs to configure the communication interface to the host (UART/SPI) and to the stacked devices, as well as to enable/disable the automatic host wake-up function. The BQ79616EVMs can also be configured using the GUI to monitor cells and other analog data channels, control balancing, and monitor details of any faults.
