BQ40Z50: BQ40Z50 FUSE故障

Part Number: BQ40Z50

1:BQ40Z50 4串电池,如果焊接V1V4之后再焊接V2V3就会出现FUSE报错问题烧保险丝,怎么设置取消保险丝检测功能呢,灯焊接好之后再开启?

2:FUSE报错之后FUSE标志位=1,怎么回复=0;状态

    The FUSE pin of the BQ40Z50 is designed to ignite the chemical fuse if one of the various safety criteria is violated. The FUSE pin also monitors the state of the secondary-voltage protection IC. Q5 ignites the chemical fuse when its gate is high. The 7-V output of the bq294700 is divided by R16 and R6, which provides adequate gate drive for Q5 while guarding against excessive back current into the bq294700 if the FUSE signal is high. Using C3 is generally a good practice, especially for RFI immunity. C3 may be removed, if desired, because the chemical fuse is a comparatively slow device and is not affected by any sub-microsecond glitches that come from the FUSE output during the cell connection process. If the AFEFUSE output is not used, it should be connected to VSS.
