The BQ76922 device integrates a voltage ADC that is multiplexed between measurements of cell voltages, an internal temperature sensor, up to five external thermistors, and also performs measurements of the voltage at the VC5 pin, the PACK pin, the LD pin, the internal Vref used by the coulomb counter, and the VSS rail (for diagnostic purposes). The BQ76922 device supports measurement of individual differential cell voltages in a series configuration, ranging from 3 series cells to 5 series cells. Each cell voltage measurement is a differential measurement of the voltage between two adjacent cell input pins, such as VC1–VC0, VC2–VC1, and so forth. The cell voltage measurements are processed based on trim and calibration corrections, and then reported in 16-bit resolution using units of 1mV. The raw 24-bit digital output of the ADC is also available for readout using 32-bit subcommands (the 24-bit data is contained in the lower 3 bytes of the 32-bit data, and is sign-extended to create the upper byte). The cell voltage measurements can support a recommended voltage range from –0.2V to 5.5V. If a cell voltage that exceeds a level of 5 × V_REF1 (approximately 6.06V) is applied, the device may report a value of –6.06V (and the cell voltage raw counts similarly would report a value of –8388608). For best performance, it is recommended to stay at a maximum input of 5.5V. The 16-bit cell and VC5 (stack), PACK, and LD pin voltage measurements are available by using the commands listed below.
