Hi,
Is the PACK connection to the BQ40z50 used for anything other than getting the device out of shutdown mode? I'm wondering if I can put a FET in-line with the pack connection to the BQ (between BQ & P+, not between P+ and the DSG/CHG FETs). If I can do this, I can use a processor to control when the pack wakes up, rather than have it automatically wake as soon as voltage appears on P+.
Obviously a FET would drop 0.7-1.5V so the pack voltage measurement would be inaccurate but that wouldn't be an issue for my application, provided I can be sure the PACK measurement is not used for anything other than wakeup.
Thanks
