如果需要，可以使用其他值。注意所示的25ppm/C温度系数。你可以校正公差，但也许不能校正漂移。您通常需要低电流和现成的组件。
关于R47您不能用NTC或者PTC，you would prefer stable resistors over temperature for the voltage divider. For a general pull up or pull down resistor you may not care if you have 100ppm/C or more change but here you might want good performance.
BAT pin的电压范围您可以看一下数据手册的电器表格。
