安森美半导体推出全集成锂离子电池充电器,因应下一代能效需求  Japanese Korean

可编程器件提供更快速的充电,延长便携电子产品电池使用时间

1381_NCP1851 Fully Integrated Li-Ion Battery Charger

2012年8月28日 – 应用于高能效电子产品的首要高性能硅方案供应商安森美半导(ON Semiconductor,美国纳斯达克上市代号:ONNN) 推出完全可编程的锂离子(Li-Ion)开关电池充电器,此器件经过了优化,用于提升智能手机、平板电脑及其它手持设备的能效。 NCP1851 大幅缩短充电时间,延长电池使用时间,并增添了先进的启动功能。

这器件提供1.6安培(A)充电能力,尺寸仅为2.2 x 2.55 mm,用于符合USB标准的最新输入电源及大容量电池,能在90分钟内完成1,650毫安时(mAh)、4.2伏(V)锂离子电池的完整充电周期。

安森美半导体接口及电源IC分部总监Thibault Kassir说:“强固性、高昂能效及快速充电时间已是当今高性能、超空间受限型应用设计人员的先决要求。NCP1851单芯片方案能简单地融入到最新USB充电设计中。它具有的快速充电时间性能及先进的功能组合, 使我们已从主要客户获得此器件的设计中标。”

NCP1851集成了动态电源路径管理功能,在电池电量低的情况下能迅速导通系统,帮助装足已深度放电的电池。这器件的内部结温传感器及外部负温度系数(NTC)热敏电阻通过将专用中断传达给I2C控制总线,确保系统安全充电。NCP1851提供USB OTG模式,为插入到USB端口的电源配件,免除须要另一个升压转换器。

封装及价格

NCP1851采用25凸点倒装式CSP封装,总平面尺寸仅为2 .2 mm x 2.55 mm,最大厚度为0.6 mm。这器件每3,000片批量的单价为1.25美元。
