BQ35100: BQ35100 sense resister value

Part Number: BQ35100

Hi 

I have a query about the sense resister need your help.

1. If I use the 100m Ω sense resister, what is the minimum current it can detected? Does it can detected the 8uA/2ms current?

2. If I  use the 25m Ω sense resister, what is the minimum current it can detected?

Waiting for your reply.

Thanks

  • For the correlation between the sense resistor and minimum sensible current for this device, it is the voltage generated by an 1mA flow through a 4.768mOhm sense resistor, when using a 100mOhm resistor, a 4.768uV LSB is 0.048mA current, but it would be only displayed as 0 in Current() register until the actual current is greater than 1mA
