The bq76920 device supports up to 5-series cells or typical 18-V packs, the bq76930 handles up to 10-series cells or typical 36-V packs, and the bq76940 works for up to 15-series cells or typical 48-V packs. Avariety of battery chemistries may be managed with these AFEs, including Lithium Ion, Lithium ironphosphate, and more.Through I2C, a host controller can use the bq769x0 to implement many battery pack managementfunctions, such as monitoring (cell voltages, pack current, pack temperatures), protection (controllingcharge/discharge FETs), and balancing. Integrated A/D converters enable a purely digital readout ofcritical system parameters, with calibration handled in TI’s manufacturing process.
