Can the bq40z50 be used with a sense resistor value lower than 1 milliohm? We have an application that has a steady 5A-30A current draw with pulses, from 300mS-1500mS long, of 80A-150A occurring occasionally.
With an input voltage range of +/-100mV the coulomb counter will be unable to properly handle these pulses if we use a 1 milliohm sense resistor. Can we reliably go down to 0.75 or even 0.5 milliohms?
Or, perhaps, can we use a 1 milliohm resistor and just have the pulses not read accurately? Depending on how the IT algorithm handles things like this, could the bq40z50 deal with these pulses and still keep accurate track of SOC since the pulses are so short?
