BQ24259: electronic load mode selection

Part Number: BQ24259

Hi team,

     I get simple questions that how to set the mode of electronic load when I want to test the CC mode of bq24259 and how to set the mode of electronic load when i test the CV mode of bq24259?



  • Hi Nan, 

    Ideally they would want to use a sourcemeter (such as a Keithley 2400) in constant voltage mode to simulate a battery for both CC mode and CV mode.

    If they are to use an electronic load for both CC mode and CV mode they will want to set the electronic load to constant voltage. For CC mode set it to a value in the fast charge phase, such as 3.5V. Then when they want to test CV mode they should set the electronic load voltage equal to their VREG setting (default 4.2V). 

    Best Regards,
