    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.
