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.

●## Description
●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.
