我在应用BQ40Z50时,遇到一些问题:数据电平(第九位)有拉不低现像,时钟有时也不高不低。如下图:望各位大神解答,谢谢!
When I use BQ40Z50, I encounter some problems: data level (No. 9) can not be pulled down, and the clock is sometimes not too high or too low. The following picture: I hope you can answer, thank you!
应用电路路如下图:电池输出直接DSP,内部上拉到1.8V
The application circuit is as follows: Battery output direct DSP, internal pull-up to 1.8V

这个应该不是芯片引起的。请检查主机行是否有问题。如果遵循参考设计,芯片应该不会与通讯系统有问题。

今天用EV2400(官方电池调试工具盒)单独读电池电量,也有同样的情况,只是轻微很多。
The same is true today with EV2400 (official battery debugging kit) reading battery power alone, but much slightly.
