BQ7693001DBT

The BQ7693001DBT is a robust Analog Front-End IC for next-generation high-power systems. It is designed with low power in mind sub-blocks within the IC may be enabled/disabled to control the overall chip current consumption and a SHIP mode provides a simple way to put the pack into an ultra-low power state. BQ76930 handles up to 10- series cells or typical 36V packs. A variety of battery chemistries may be managed with these AFEs, including Li-ion, lithium iron phosphate and more. Via I2C, a host controller can use the bq769x0 to implement many battery pack management functions, such as monitoring (cell voltages, pack current, pack temperatures), protection (controlling charge/discharge FETs) and balancing. Integrated A/D converters enable a purely digital readout of critical system parameters, with calibration handled in TI\x92s manufacturing process.
