BQ78350-R1: Current scaling?

Allen Wachter

Part Number: BQ78350-R1

My customer would like to use current scaling to read more than 32767mA. However, it is not completely obvious which parameters this affects for current protection limits and read back values. Can you direct to some information which covers this in detail?

Thanks!

Hi Allen,

For the BQ78350-R1, you can scale the current by calibrating to a different value. For example, you can provide a 10A load, but tell the device that the load is 1A. You then to to scale all of your current and capacity settings (units in mA and mAh) in data flash.
