您好，关于BQ4050 sleep里通过大电流快速唤醒功能有如下两个问题，烦请解答一下，谢谢。
1）datasheet上说“The device can exit SLEEP mode if enabled by the presence of a voltage across SRP and SRN”，这个功能除了设置Power:Wake Comparator的值，是否还需要额外设置某些使能位？
2）datasheet上说"This allows the gauge to wake up quickly in response to a higher current detection." 这里说的wake up quickly大概是多久? 或者说这样唤醒后到能正常采样电流大概需要多久？
Star Xu：
您好
1，TRM上没有找到额外的设置参数。
2，wake up时间请参考数据手册6.9 Electrical Characteristics: Current Wake Comparator
