BQ24195: TS Pin resistor values

JAP

Part Number: BQ24195

Is there a mistake in datasheet on page 19 where TS pin resistor values are calculated? Should the value for RT1 be 5.25k? At least that's what I get when using spreadsheet calculation tool. Value in datasheet for RT1 is now 5.52k.

Rgds,

Juha,

It is correct. Please refer to the calculation below.

Thanks,

Ning.

Yes, I have seen that. How I understand this is that RT1 in datasheet is R8 in spreadsheet. Correspondingly RT2 in datasheet is R9 in spreadsheet.

In addition, when using the equations on page 19 in datasheet, result for RT1 value is 5.25, not 5.52. Please double check this. Can you also explain the meaning of R_HTF (40C) in spreadsheet?

Juha,

RT1 should be 5.25kohm on the d/s. Please ignore R_HTF (40C) in the spread sheet.

Thanks,

Ning.
