Texas Instruments introduced a 3-MHz, switch-mode battery charge management integrated circuit for portable electronics that can be charged from an adaptor or a USB port. The tiny 2 mm x 2 mm switching charger, the bq24150, significantly improves charge time, reduces power dissipation and cuts board space in half compared to typical implementation with linear chargers. |

Linear Technology Corporation introduces the LTC4009, a fast-charge 4A capable, high efficiency switchmode battery charger controller for multiple battery chemistries which minimizes power dissipation without compromising board space. The LTC4009 supports Li-Ion/Polymer, NiMH, NiCd and sealed lead acid battery chemistries in multi-cell configurations. AC adapter current limiting maximizes the charge rate for a given fixed input power level, allowing the end product to operate at the same time the battery is charging without complex load management algorithms. |
