Part Number: BQ40Z80 Other Parts Discussed in Thread: BQSTUDIO
我使用bq40z80芯片完成了电量计黄金学习,将导出的参数向新板子中导入时,点击write all,会出现写入错误,很多参数出错。比如下图中system data中很多参数变成了ff。再重新设置某个参数,会提示a read of data written failed comparison。下面附件是我导入的参数文件(因上传失败,将.gg.csv后缀改为了txt),麻烦帮我分析一下问题…

Part Number: BQ40Z50 Hi TI Team:
我们有个产品方案使用BQ40Z50+BQ296107,电量计部分的原理图与TI参考设计一致。近日有1个产品从用户处退回来,出货时间是21年,发现是Fuse熔断,产品对于Fuse只设定单节过压时BQ296107动作,所以虽然线路上BQ40Z50的Fuse pin有预留,但实际PF_EN和二级保护设定都disable,做了以下确认:
1、三端Fuse拆开,发现是两边都有熔断,现象符合Fuse pin到地,Fuse发热丝发热导致熔断导致;
2…
