Summit Expands Family of Tiny, Programmable Switch-mode Battery Chargers Featuring Fast and Efficient “Green” Technology
Summit Microelectronics has expanded its third-generation programmable battery charger integrated circuit (IC) family with the introduction of the SMB329.
Based on the award winning, highly-integrated SMB339 family, the SMB329 integrates additional features, such as “instant-on”, even with a dead battery, and real-time charge current monitoring. Like its predecessors, the SMB329’s parameters are programmable in non-volatile memory for power-up configuration, and in volatile memory for in-system adjustments via the I2C host interface. In addition, high-efficiency switch-mode operation and TurboCharge™ mode allow for thirty to fifty percent shorter charging times, while reducing thermal dissipation and wasted power by 80%.
The SMB329 supports all relevant interface (USB2.0, USB OTG, USB charging, etc.) and safety (IEEE1725, JICS8714, etc.) standards, resulting in reduced development time and cost associated with system compliancy efforts. Additionally, the SMB329 supports the industry’s environmental and Green efforts by enabling universal USB charging, eliminating electronic waste while dramatically reducing energy usage.
