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 performs measurements of the voltage at the VC5 pin, the PACK pin, the LD pin, the internal REG18 LDO voltage, and the VSS rail (for diagnostic purposes). The BQ76922 device supports measurements 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 on. 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 cell voltage measurements can support a recommended voltage range from –0.2 V to 5.5V. The voltage ADC saturates at a level of 5 × VREF1 (approximately 6.06V) when measuring cell voltages, although for best performance, stay at a maximum input of 5.5V.
