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, such as
BQ7961x-Q1 devices. The BQ79600EVM can be powered through a 5-V source such as 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 master 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 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.
The BQ79600EVM is controlled using a PC-hosted GUI. Communication between the PC and the
BQ79600EVMs is via an USB2ANY UART/SPI interface. 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.
1.1
Key Features
This EVM includes the following features:
•
UART interface for communication to the host, configurable through jumpers
•
SPI interface for communication to the host, configurable through jumpers
•
Supports host communication through FTDI (UART only), USB2ANY, or TMS57012 microcontroller
(direct connection to XL2-TMS57012 LAUNCHPAD boosterpack)
•
Isolated differential daisy chain communications with optional ring architecture
•
Jumpers to configure 5-V or 12-V options (use 5-V option when powering through a regulator/PMIC
device and 12-V option when powering directly from 12-V battery and to use automatic host wake-up
function)
•
LEDs to indicate when the device is awake and when there is an unmasked fault
