Summit Introduces Industry’s First Battery Charger to Enable True Universal USB Charging While Minimizing Solution Footprint
Summit Microelectronics has introduced its third-generation programmable battery charger integrated circuit (IC) for single-cell Li-Ion and Li-Polymer powered systems.
The SMB339 integrates the largest feature set in the industry, including compatibility with all relevant industry standards: USB 2.0 Specification, USB "On-The-Go" Supplement, USB Battery Charging Specification 1.0, IEEE1725 Standard, Chinese USB Charging Specification, and others.
This innovative charging solution automatically adapts to and delivers the fastest battery charging from any power source (USB host/hub, AC/DC, etc.) without the software required in typical implementations.
Additionally, high integration reduces bill-of-material count/cost and solution size to levels comparable to inferior linear charging solutions, while cutting power dissipation by 80percent. Like all Summit’s solutions, digital programmability is built-in, providing design and system flexibility at no additional cost.
