TPS2111: TPS2111 spice model & VSNS : min , typ , max values with custom threshold

Semi Tehrani
Prodigy 30 points
Part Number: TPS2111

Tool/software:

Hi , 

It would be great to know where I can download the pspice model for TPS2111 . I will be using TI Spice simulation tool.

In order to use Auto-Selecting for a Dual Power supply Application ( Data sheet page 15 figure 13)  , The voltage at VSNS has to follow VSNS threshold parameters (page 4) min , typ , max?

The user defined threshold could be for example 4.5V?

Please, also share a link to download the spice model for this part. 

thanks,

Semi

    Hi Semi,

    PSPICE model is not available. 

    In order to use Auto-Selecting for a Dual Power supply Application ( Data sheet page 15 figure 13) , The voltage at VSNS has to follow VSNS threshold parameters (page 4) min , typ , max?

    Yes. You can design considering typical threshold. 

    1. If you are using resistor divider from vin to sns pin then you can design such that at Vin = 4.5V, sns voltage is near it's threshold.
