TI’s fully integrated super capacitor manager optimizes battery performance, lifetime and safety
IC enables users to make battery pack lifecycle decisions
based on accurate state-of-health information
Bangalore (June 10, 2011) – Texas Instruments Incorporated (TI) 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 charge r 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:
