Hello,
I am wondering what is the best method of implementing a physical kill switch (SPST)? My application requires some sort of battery disconnect when a physical switch is actuated by a user. Switch must be placed on the low side of the battery. I would like to avoid placing it directly on the power rails as the switch has a low current rating (< 2 A, battery capable of 10 A). My idea was to use a switch between BAT and battery cathode; When the kill switch is pressed, the contact is opens and the BQ2973 power down. What I want to know is when the BQ2973 powers down, is it safe to consider the battery isolated due to the CHG/DSG MOSFETs being open?
