3月23日星期三，8：30-10：10，下一代锂离子电池管理解决方案，大大延长电池寿命，降低系统成本和复杂性Maatt Tyler
随着便携式电子设备的快速发展和附加的功能，对这些设备的电池储备的压力越来越大。
工程师希望从他们正在开发的便携式设备中提供更高水平的性能，同时保持在紧凑的外形尺寸范围内，此外，还必须应对成本和上市时间的压力。
这些压力在智能手机业务中更为突出。
消费者对更大连接性的渴望意味着即使智能手机生态系统的简单部分现在也必须具有低成本的嵌入式智能。
硅技术的发展推动了智能化程度的提升 - 从而进入了广泛的微控制器单元，连接芯片和应用处理器IC。
然而，电源电压急剧下降，而单节电池电压随着更新的锂离子电池技术的广泛采用而增加。
此外，这些IC所基于的深亚微米工艺意味着它们具有更高的静态漏电流。
对通过其提供电力的USB互连的电力需求正在继续增加。
USB标准的更新导致电源管理模块内的更高智能（因此可以利用新的充电模式）。
这意味着电源管理模块实际上可能是系统整体能耗的主要贡献者。
因此，需要针对电力系统架构和系统划分采取新方法。
通过这些，可以实现偏置和监控系统的寄生功率损耗的显着降低，同时还显着降低静态功耗并使更短的充电时间受益。

Next Generation Li-Ion Power Management Solutions That Dramatically Extend Battery Life and Reduce System Cost and Complexity
Matt Tyler

With portable electronics rapidly evolving and additional functionality being incorporated, there is increasing strain being placed on the battery reserves of these devices. Engineers look to deliver elevated levels of performance from the portable equipment that they are developing, while keeping within the confines of compact form factors and, in addition, having to cope with cost and time to market pressures. Nowhere are these pressures more acute than in the smartphone business.
Consumers hunger from greater connectivity means that even simple parts of the smartphone ecosystem must now have low cost embedded intelligence. The progression of silicon technology is driving incorporation of this elevated degree of intelligence - it is thereby finding its way into a broad array of microcontrollers units, connectivity chips and application processor ICs. However, the supply voltages have sharply decreased, while single cell battery voltages have increased with wider adoption of newer Li-Ion technologies. Furthermore, the deep-sub-micron processes on which these ICs are based mean that they are blighted with higher quiescent leakage currents.
Power demands being placed upon the USB interconnects, through which power is delivered, are continuing to rise. Updates to USB standards are leading to greater intelligence within power management blocks (so that new charging modes can be utilized). This means that power management blocks can actually be a major contributor to the system’s overall energy consumption. New approaches therefore need to be taken with regard to power system architecture and system partitioning. Through these it will be possible to achieve substantial reductions in parasitic power loss for bias and supervisory systems, while also markedly lowering quiescent power consumption and enabling shorter charging times to be benefitted from.
