TPS2492: Excel spreadsheet calculation tool - open up for use with the *****92 part

K Henrich
Prodigy 70 points
Part Number: TPS2492

Hi,

In using this tool and reading the datasheet, i'm led to believe that the charging current needs to be updated to use with the 2492.  I also see in the videos that both under and overvoltage parts are calculated.  In the J version they are not.  Is there a way to fix both of these issues?  The spreadsheet is password protected so, I cannot fix this myself.

Thanks

    Hi Henrich,

    Thanks for reaching out!

    The functional behavior for TPS248x, TPS249x family of devices is same and hence we have single design calculator for all of those devices. For undervoltage, overvoltage threshold calculations with TPS2492, please refer application example in the datasheet (Section 5. Choose the Turn-On and Over-voltage Divider) and let me know if you have issues. 

    The design sheet can be unlocked with password TPS249x

    Best Regards, Rakesh

    Rakesh,

    Thanks for the reply.  I may be missing it, but I cannot find a cell to enable the overvoltage calculator.  The file I have is

    TPS249x/8x Design Tool- Rev. B                            

    It does not have option A or B for calculating the dividers as can be seen below.

    Thanks

    Ken

    Hi Henrich,

    Sorry, overvoltage threshold calculations are not included in this calculator. 

    For overvoltage threshold calculations with TPS2492, please refer application example in the datasheet (Section 5. Choose the Turn-On and Over-voltage Divider) and let me know if you have issues. 

    Best Regards, Rakesh
