Other Parts Discussed in Thread: TPS37, TPS3760, TPS38
Hello
The datasheet says that the delay can be adjusted from 1.25 ms to 10 s.
What happens when I put a C_T capacitor that exceeds C_T=175*10=1.75uF?
From a different question/answer in this forum, I know that 14s is possible. (2.45uF)
But what happens if I put e.g. 4uF?
Will the circuit still work as intended?
Will the delay be capped at 14s?
Will the delay still increase with increasing capacitance, but with higher tolerance on the delay?
Or is it possible that the the chip will never de-assert \RESET or even exhibit a delay shorter than 14s?
I am asking because of the following:
For my application it is important, that the delay is not shorter than e.g. 10s.
But since the time delay of the TPS3808 is apparently only accurate up to +/-30%, I would need to have a nominal delay of 14.3s, such that 0.7*14.3s>10s.
And 14.3s is outside of the specifications/datasheet.
Thanks for the support!!
