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
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.
