BQ24610充电电流太小的问题

One reason can be the charge current setting is greater than the input current regulation setting. Once the input current regulation is reached, the current will be regulated at the input current regulation. Another reason is that the charge current setting is higher than the input source can supply. In this case, input voltage will droop and input voltage will be clamped by VINDPM threshold.

Please make sure check

1. charge current setting is lower than input current regulation setting

2. input power source is sufficient to supply the charge current setting

Hi
现在的问题是否是你所设置的充电电流与实际测量到的充电电流出现偏差？
如果是你需要确认sense电阻的layout, 这个对充电电流影响很大。

嗯，是的，实际充电电流是跳变的，且最大只有0.3A左右，我设置的理论充电电流最大为5A.

下图是我的layout,,这样布局会不会有问题？图二圈着的地方是sense电阻。

你好，我检查了这两点，我设置的最大充电电流为5A，且确定电源能提供足够的充电电流，但依然有问题。

你好，我检查了这两点，我设置的最大充电电流为7A，且确定电源能提供足够的充电电流，但还是有问题。
