想用BQ24161B,但是芯片手册中没有BATGD这个管脚的定义,这个管脚应该如何接线呀。看名字,象是接到电池的负端。

从PDF文档来看,跟24160的INT功能是一样的吧?从技术规格书的第5页来看,第7脚功能描述也是INT的功能,至于这个BATGD难道是BATGOOD?技术规格书第35页的图上,BQ24161的典型应用里,也是画的INT,而不是BATGD,是不是也代表这两个功能一致?

Datasheet的page 25有对于这个pin脚的详细描述
9.3.18 Good Battery Monitor The bq2416xx contains a good battery monitor circuit that places the bq2416xx into high-z mode if the batteryvoltage is above the BATGD threshold while in DEFAULT mode. This function is used to enable compliance tothe battery charging standard that prevents charging from an un-enumerated USB host while the battery is abovethe good battery threshold. If the bq2416xx is in HOST mode, it is assumed that USB host has been enumeratedand the good battery circuit has no effect on charging.

谢谢,这个脚该怎么连线呢。
