We are currently evaluating the BQ27621 for our low-power application and have some questions we could not figure out via the doc.:
1. There is a clear relationship between the different modes (Normal, sleep, etc.), how the gauge operates, and the current draw by the gauge. However, how does the POWERMIN fit: How does it impact the different modes when set? And what current draw reductions can we expect in the different modes?
2. The clock stretching on all i2c traffic when in SLEEP and HIBERNATE is worrying. With e.g. bq27441 this is specified in the datasheet (Section 184.108.40.206) as <100 us, do you have this number for bq27621? How much is added to this stretch when POWERMIN is enabled (if any)?
