BQ27426: Current measurement capacity

Part Number: BQ27426

Hello!

I'm trying to find the current measurement capacity of BQ27426. I believe its calculated as follows:

Imeasured=(Vsrn-Vsrp)/Rsense

From the datasheet, following are the values which are gathered: (Vsrn-Vsrp)=2V; Rsense=10mohm. Does this mean that the maximum current measurement capacity is 200 A? Please indicate any mistakes with my understanding of current measurement.

Also, what is the max. charge discharge current for BQ27426EVM-738? Some EVM datasheets list these limits, but I couldn't find that in the datasheet of this product.

Thanks!

  • hi Ved,
    Data sheet has this as bat+/-25 mV. So effectively 25mA/10mom.

    Our EVMs are designed to handle 2A.

    thanks
