The Texas Instruments bq33100 Super Capacitor Manager is a fully integrated, single-chip, solution that provides a rich array of features for charge control, monitoring, and protection, for either 2, 3, 4, or 5 series Super Capacitors with individual capacitor monitoring and balancing or up to 9 series capacitors with only the stack voltage being measured. With a small footprint of 7.8 × 6.4 mm in a compact 24-pin TSSOP package, the bq33100 maximizes functionality and safety while dramatically increasing ease of use and cutting the solution cost and size for Super Capacitor applications.For all available packages, see the orderable addendum at the end of the data sheet.

Using its integrated high-performance analog peripherals, the bq33100 measures and maintains an accurate record of available capacitance, state-of-health, voltage, current, temperature, and other critical parameters in Super Capacitors, and reports the information to the system host controller over a 2-wire SMBus 1.1 compatible interface.
The bq33100 provides firmware controlled protection on overvoltage, overtemperature, and overcharge along with hardware controlled protection for overcurrent in discharge and short circuit protection during charge and discharge.
