Description for the BQ33100
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 mm × 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.
Using its integrated high-performance analog peripherals, the BQ33100 battery manager 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.
