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……
