By Staff -- 5/15/2008

Popular features that caught readers' eyes: the trend to speed up battery-recharge time through either supercapacitor usage or sophisticated charging algorithms, the move toward accurate fuel gauges for portable devices, and the integration of authentication circuits into charging ICs.

• Cap-xx Ltd HS and HW: Supercapacitors deliver 100 times the power of batteries
• Dallas Semiconductor DS2786: Stand-alone fuel gauge reports battery capacity without a full-charge cycle
• Advanced Analogic Technologies AAT4620: Integrated supercapacitor charger IC reduces charge time
• Advanced Analogic Technologies AAT3663: Battery-charger IC monitors internal die temperature
• Maxim Integrated Products DS2784: Fuel gauge combines a lithium protector and SHA-1 authentication
