cnZHCSBL6B–SEPTEMBER2013–REVISEDNOVEMBER20145说说明明((续续))它的低阻抗电源路径对开关模式运行效率进行了优化、减少了电池充电时间并延长了放电阶段的电池寿命.
具有充电和系统设置的I2C串行接口使得此器件成为一个真正的灵活解决方案.
该器件支持3.
9V-6.
2VUSB输入电源,包括具有6.
4V过压保护功能的标准USB主机端口和USB充电端口.
该器件符合USB2.
0和USB3.
0电源规范,具有输入电流和电压调节功能.
为了设定默认输入电流限值,bq24296从系统检测电路(如USBPHY器件)获得结果,而bq24297将通过D+/D-检测功能检测符合USB电池充电规范1.
2的输入电源.
此外,bq24297还会检测非标准2A/1A适配器.
该器件还具有快速启动功能和高达1.
5A的精确限流能力,能够为VBUS提供4.
55V至5.
5V(默认5V)可调电压,支持USBOn-the-Go运行.
电源路径管理将系统电压调节为稍稍高于电池电压,但是又不会下降到低于3.
5V最小系统电压(可编程).
借助于这个特性,即使在电池电量完全耗尽或者电池被拆除时,系统也能保持运行.
当达到输入源电流或电压限值时,电源路径管理自动将充电电流减少为零,然后开始对电池放电,直到满足系统的电源需求.
这个充电模式操作可保证输入源不会过载.
此器件在主机控制不可用时开始且完成一个充电周期.
它分三个阶段对电池进行自动充电:预调节、恒定电流和恒定电压.
在充电周期的末尾,当充电电流低于在恒定电压阶段中预设定的限值时,充电器自动终止.
之后,当电池电压下降到低于再充电阈值时,充电器将自动启动另外一个充电周期.
此充电器件提供针对电池充电和系统运行的多种安全特性,其中包括负温度系数热敏电阻监视、充电安全性定时器和过压/过流保护.
当结温超过120°C(可设定)时,热调节减少充电电流.
STAT输出报告充电状态和任何故障条件.
当故障发生时,INT立即通知主机.
bq24296和bq24297采用24引脚4x4mm2超薄VQFN封装.
