bq27742-G1 -- need more information

Dear Sir Madam

Dear Stefan

As discussed earlier, the issue we are facing with BQ28Z610 as it works only in the I2C master mode.we want to replace Fuel gauge (for new design) in place of BQ28Z610.

 

-          BQ28Z610 fuel gauge is the only works in I2C master mode, which is not suitable in our application.

-          We are searching for new fuel gauge and   (http://www.ti.com/lit/ds/symlink/bq27742-g1.pdf), which seems suitable for our application.

 

We have few queries regarding bq27742-G1 fuel gauge as listed below,

 

  1. What is the value of Sense resistor if we are using battery and Solar Panel as below configurations.
    1. Battery – 3.7V, 4600mAH (For Master) & 3.7V, 2200mAH (For Slave)
    2. Solar Panel – 6V, 6W (For Master) & 6V, 3.5W (For Slave)
    3. In Datasheet Page No-31, Typical Application (Table 11), Device Chemistry

As mentioned in this Point , “Should be configured using TI-supplied Battery Management Studio software”, is there any hardware (EVM) require for that?

  1. Share your valuable views weather bq27742-G1 Fuel gauge seems suitable for our application?

 

Kindly find attached block diagram of our application.

 

Please let me know if any other information is require form our end.

 

I look Forward to hearing from you soon.

Thanks for understanding.
