    摘要:USB接口的便携设备充电,传输数据时的能力。但对于高容量的电池,USB主机和集线器的有限输出电流大大延长充电时间。供电的USB集线器和USB主机提供高达500mA。未通电的USB集线器提供不超过100mA。可以提供一个独立的AC适配器充电电流。最方便的解决方案,无论从USB端口或AC适配器。用户可以从笔记本电脑USB端口充电行驶时,使用AC适配器,其更快的电荷,当在家中或办公室。Maxim>AppNotes>BATTERYMANAGEMENTPOWER-SUPPLYCIRCUITSKeywords:USBcharger,LithioumIoncharger,LichargerDec10,2002APPLICATIONNOTE1815AddCurrentBoosttoUSBChargerDrivenbyanACAdapterAbstract:AUSBinterfaceiscapableofchargingaportabledevicewhiletransferringdata.Butforhigh-capacitybatteries,thelimitedoutputcurrentofUSBhostsandhubsgreatlyextendsthechargingtime.PoweredUSBhubsandUSBhostssupplyupto500mA.UnpoweredUSBhubssupplynomorethan100mA.AseparateACadaptercansupplychargingcurrent.ThemostconvenientsolutionworksfromeithertheUSBportoranACadapter.TheusercanchargefromanotebookUSBportwhentraveling,andusetheACadapter,withitsfasterc……

    摘要:DS2761和DS2762的高精度电池监视器,提供Li+电池的监测和保护。这些器件具有两种电源模式:主动和睡眠。而在主动模式下,设备不断监视系统,并提供锂离子保护。在休眠模式下,这些活动将停止。有几种情况,可以进入休眠模式主动模式过渡的设备:低DQ的电压条件下,和swap命令发出。有另一组条件,可以从睡眠模式转换到主动模式的设备:DQ的,PS的下降沿上升沿,附带一个充电器,并发出swap命令。PMOD位,斯文位,DQ引脚和电池电压作用状态,充电控制(CC)和放电控制(DC)引脚如何反应时起床。本应用笔记提供起床在所有可能的情景发生的事情的细节。Maxim/Dallas>AppNotes>BATTERYMANAGEMENTKeywords:DS2761DS2762DS2760wakingupactivemodesleepmodebatterymanagementLiIONLi+Li-May04,2004IONAPPLICATIONNOTE3225WakingupaDS2761/DS2762TheDS2761andDS2762HighPrecisionBatteryMonitorsprovidemonitoringandprotectionforaLi+cell.Thesedeviceshavetwopowermodes:ActiveandSleep.WhileinActiveMode,thedevicescontinuallymonitorthesystemandprovideLi+protection.WhileinSleepMode,theseactivitiescease.ThereareseveralconditionsthatcantransitionthedevicesfromActiveModeintoSleepMode:alowDQ,anundervoltagecondition,andtheissuingoftheSwapcommand.ThereisanothersetofconditionsthatcantransitionthedevicesfromSleepModeintoActiveMode:arisingedgeofDQ……
