Original question:

BQ35100: 关于BQ35100的一些问题，满足低功耗要求的情况下如何检测所有放电活动？

BQ35100: BQ35100的读写操作是否会影响精度

Part Number: BQ35100

我之前有咨询得知BQ35100在flash写操作时，由于耗流大，会导致内部LDO电压下降，这个对于芯片工作会有影响吗？比如这是否会导致此刻库仑计的电流或者电压的读数的误差？写操作时独到的参数与没有写操作时读到参数不一致？

    您好，由于问题比较复杂，我需要询问更了解这款芯片的TI工程师，再帮您解答，稍后回复。

    您好，请参考下面内容

    Generally there's not a large amount of flash writes occurring during normal operation and while the gauge is taking a measurement, if the supply for the gauge is a resistive path and the voltage drops it could cause problems with the readings or gauge functionality, as long as the nodes are within recommended operating conditions even in a higher current state when writing flash the gauge should operate normally.
