TI Introduces Fully Integrated Super Capacitor Manager
Texas Instruments Inc. (TI) introduced what it says is 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.
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 include: 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; and I2C and SMBus communications are widely used communication protocols that match many host processor capabilities.
The bq33103 super capacitor manager is available now in a 7.8 x 6.4mm TSSOP package, priced at $4.65 in quantities of 1,000.

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
