BQ500212A TID BOM – few questions about values not matching up

Other Parts Discussed in Thread: BQ500212A, CSD25310Q2

Hi team,

 

I have a customer that is going through our BOM for the TIDA-00334 wireless power supply transmitter with the BQ500212A, and there are a few values that are not making sense:

http://www.ti.com/tool/TIDA-00334

 

BOM: http://www.ti.com/lit/pdf/tidrb62

 

Looking at page 2, these resistor line items have “values” and the “description” for them don’t match?

 

-R24 

-R33  

-R70/71/72/73

-R99

 

Then lastly, for the “Q1 and Q3” line item, it shows CSD25302Q2, but there is no TI product folder or datasheet on this. Is that a typo or what can we say about that particular MOSFET?

 

 

Thanks in advance for the help,

Billy

    The errors will be corrected on the next revision to the BOM, it should be on line in early Jan.

    -R24 – Value should be 48.7k ohms, but recommend Do Not Populate.
    -R33 – Value should be 243 ohms
    -R70/71/72/73 – Value should be 0 ohms
    -R99 – Value should be 86.6k, but recommend Do Not Populate
    -Q1 and Q3 – CSD25302Q2 is obsolete and replaced by CSD25310Q2

    NOTE: R24 and R99 support the FOD protection feature and values will need to be determined on final design. See bq500212A data sheet for more information on FOD Calibration.
