SLUSE91B September 2020 – January 2022 BQ769142
PRODUCTION DATA
The BQ769142 device integrates three serial communication interfaces—an I2C bus, which supports 100-kHz and 400-kHz modes with an optional CRC check, an SPI bus with an optional CRC check, and a single-wire HDQ interface. The default configuration for the BQ769142 device is I2C mode, while other versions of the device may have a different default configuration. The communication mode can be changed by programming either the register or OTP configuration. The customer can program the device's integrated OTP on the manufacturing line to set the desired communications speed and protocol to be used at power up in operation.
