DescriptionThe Texas Instruments BQ33100PWR Super Capacitor Manager is a fully integrated, single-chipsolution that provides a rich array of features for charge control, monitoring, and protection foreither 2-, 3-, 4-, or 5-series super capacitors with individual capacitor monitoring and balancingor up to 9-series capacitors with only the stack voltage being measured. With a small footprint of7.8 mm × 6.4 mm in a compact 24-pin TSSOP package, the BQ33100PWR maximizes functionality and safetywhile dramatically increasing ease of use and cutting the solution cost and size for supercapacitor applications.
Using its integrated high-performance analog peripherals, the BQ33100PWR battery managermeasures and maintains an accurate record of available capacitance, state-of-health, voltage,current, temperature, and other critical parameters in super capacitors, and reports theinformation to the system host controller over a 2-wire SMBus 1.1 compatible interface.
The BQ33100PWR provides firmware-controlled protection on overvoltage, overtemperature, andovercharge, along with hardware-controlled protection for overcurrent in discharge and shortcircuit protection during charge and discharge.
