Texas Instruments BQ7693001DBT BQ7693001DBT Battery LiFePO4 Li-Ion Li-Pol Monitor IC I2C Interface 10 Cells 6 V to 25 Supply TSSOP-30

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.

• Pure digital interface
• Internal ADC measures cell voltage, die temperature and external thermistor
• Separate, internal ADC measures pack current (coulomb counter)
• Directly supports up to three thermistors (103AT)
• Overcurrent in discharge (OCD)
• Short-circuit in discharge (SCD)
• Overvoltage (OV) protection
• Undervoltage (UV) protection
• Secondary protector fault detection
• Integrated cell balancing FETs
• Green product and no Sb/Br
