集成电源开关的超低功耗实时时钟

MAX31334超低功耗实时时钟(RTC)是一款计时电流只有70nA的计时器件。其集成高侧功率传输开关，在周期工作的应用中，可通过断开系统上其他设备的电源启用超低功率空闲模式。电源开关的开/关持续时间可以通过周期性中断源来控制，例如倒数计时器（可编程范围为100ms到1hr）和警报（分辨率为1s）。电源开关也可以通过DIN引脚上的外部中断（例如来自按钮）来控制。MAX31334支持任意负载(CL)规格的多种晶振，因此该器件的可用晶振范围广泛。该器件通过I2C串行接口访问。集成的上电复位功能可确保上电时默认寄存器状态的确定性。\n\n 该器件还具有备用电源引脚(VBAT)，在主电源(V • 超低功耗实时时钟\n• 计时电流：70nA\n\n• 计时电压范围：1.1V至5.5V\n\n• 发生电源故障时自动切换到备用电源\n\n• 提供用于外部超级电容的涓流充电器\n\n\n\n\n• 带状态机的集成电源开关可延长系统电池续航时间\n• 连续电流高达500mA\n\n• 57mΩ超低导通电阻\n\n• 发生周期中断时唤醒——倒数计时器（100ms至1hr）和警报（分辨率为1s）\n\n• 发生外部中断（如按钮）时唤醒;
