DALLAS, June 9, 2011 /PRNewswire/ -- Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced the industry's first fully integrated Li-Ion battery management integrated circuit (IC) for super capacitor charge control. This single device provides comprehensive features for managing charge control; measuring capacitance and effective series resistance (ESR); and protecting either 2-, 3-, 4- or 5-series super capacitors with individual capacitor control, or up to 9-series capacitors with stack control. For more information or to place an order, visit www.ti.com/bq33100-pr.
The bq33100 maximizes functionality and safety, while dramatically increasing ease of use and cutting the solution cost and size for super capacitor applications. Battery-backed write cache applications, system bridge power and non-volatile dual in-line memory RAID controller cards need reliable super capacitor pack managers to ensure availability when the primary power fails.
Key features and benefits
Prevents surprise battery pack failures by measuring pack health conditions.
Communicates dynamic charge voltage with the charger to extend battery pack life.
Prevents damage to capacitors caused by over voltage or over temperature stress during charging.
Measures and maintains accurate record of available capacitance.
Single device manages multiple capacitor configurations: 2-, 3-, 4-, and 5-series super capacitor packs.
Integrated and programmable protection configures safety parameters to battery pack and system needs.
I2C and SMBus communications are widely used communication protocols that match many host processor capabilities.
Tools and support
TI offers a variety of tools and support to speed the implementation of super capacitor managers:
