How to define the RC values for Tdelay that configurated by FS6500 FS1B?

[Chenhaohao1]

Hello Sir,

It is difficult for me to understand how to calculate the R C values by the below calculation ; Would you please 

explain the principles in detail?  And how to define the Rtot and "e" values?

thanks!

Hi,

I have not found any additional information for this calculation, but R_TOT is defined as a parallel combination of R_INT and R_PD, “e” is an Euler’s constant (2.71828...).

Best regards,

Tomas
