采用BQ4050方案,4个LED灯做电量显示,TI推荐是5个,去掉了LED5,LED CHG THRESH1设为0%,CHG THRESH2设为25%,CHG THRESH3设为50%,CHG THRESH4设为75%,CHG THRESH5设为100%,充电测试时显示正常,当电量SOC到100%后,LED2和LED4会闪烁,LED1和LED3常亮正常,测试5个LED灯的时候是没有这个问题的,我想请教下,4个LED使用时,充满的话怎么解决其中2个闪烁问题,最好是通过设置解决问题,谢谢!

您好, LED chg thresh 5 must be set to 101%. You will not be able to do this with the bqz so it would have to be done manually with a DF write using the advanced comm tab.
here's how to change it to 101%:

Do a write block with 0x44 as command and the data in the image in the block.
您好,请参考下面内容
With the LEDCHG configured the gauge will try to blink LED5 so the LED4 threshold would need to be set so it doesn't blink until full charge, the final threshold for LED4 should be 100%.
那我CHG thresh 1-5分别如何配置?现在客户要求SOC≤25%亮一个灯;SOC≤50%亮两个灯;SOC≤75%亮三个灯;SOC=100%四个灯全亮;
您好,参数设置参考下面的表格,看一下是否还有led闪烁问题。
| CHG Thresh 1 | 25% |
| CHG Thresh 2 | 50% |
| CHG Thresh 3 | 75% |
| CHG Thresh 4 | 100% |
| CHG Thresh 5 | 101% |
