Other Parts Discussed in Thread: TL431LI, ATL431LI, TL431, TLV3012-Q1
Dear Ti Community,
For one application, I plan to use the TL431LI part in open-loop mode (for voltage comparison) and, by the way, need to perform many simulations.
So, I have several questions :
- What are the differences between the "Transient" and "Average" Spice models for this reference ?
- Then, I want to perform simulations with all worst-case conditions including manufacturing tolerance on some parameters (like the Vref dispersion accross the full temperature range with min. and max. values). Is there any Spice model available to simulate worst-case behaviour of the chip ?
- Last item is related to a very simple model I have made and for which I have question because it is not well-document within the datasheet.
-
- Did someone has any explanations about the propagation delay of 50µseconds ? It seems that this delay cannot be shorter !
- In the datasheet (Figure 21 / Page 15), there is no 50µseconds of propagation delay I have noticed in my simulation.
- So, every comment to my concern will ever be welcome !
Kind Regards,
