I2C Communication Sample Code for the bq76940 with CRC Based on the MSP430 (Rev. B)
PDF, 162 Kb, 修订版: B, 档案已发布: May 14, 2014
This application note describes how to communicate with the bq76940 family devices over I2C. The code is based on the TI MSP430G2553. The code shows how to write the CRC function which is used to verify the transaction integrity over the I2C and how to initialize the I2C engine of the G2553 and bq76940 registers as well as how to read binary data from the AFE registers and transfer the data to vol

bq769x0 boot switch alternatives
PDF, 141 Kb, 档案已发布: Dec 21, 2015
The simplified system schematic in the bq769x0 data sheet shows a boot switch to wake the bq769x0 battery monitor. While this is a simple solution, in some cases this switch will not meet the needs of the system. This application report describes proposed circuit alternatives for the boot switch that may be considered for system design.

Fault Monitoring for High-Availability Systems using the bq769x0
PDF, 937 Kb, 档案已发布: Feb 3, 2017
The bq769x0 monitor family provides a complete solution of monitoring and protection for battery voltageand current related faults, but also protects the battery system by self-monitoring for internal hardwarefaults. There are high-availability applications, such as in a drone battery management system, where thisunexpected FET turn off is undesirable. In such applications, faults like XREAD
