hello, I have a few questions about the BQ27741 chip:
1. what is the best resistance for the sense resistor if my max current is 10A? The datasheets don't seem to discuss it. The reference design uses 5m-ohm for 2A max.
2. Is the I2C address fixed at 0xAA? can this be modified?
3. Can I have a master-slave I2C bus architecture, where I have 5 BQ27741 slaves and 1 master processor? Are there any design examples of this? if I have 5 cells in series, how do I handle the different voltage levels of each cell with respect to the processor GND?
thanks
