Simulation of TPS27081A high side load switch


is there any spice model for the TPS27081 available?

I would like to include it in my global simulation.

The application is an active current limiter between a high impedance source and the large bypass capacitor of a switching regulator. Other current limiters are unsuitable, because I need an adjustable (among different products) solution in the range of about 1mA to about 50mA. Also, quiescent currents are of paramount importance, so I would like to plot the tradeoff between R1 and the leakage current.



  • Roberto,

    Unfortunately, there is no SPICE model available for the TPS27081.  We are also hard pressed to think of a similar-type device with model availability.

    At this point, I recommend you approach your local TI sales point-of -contact to discuss this opportunity in greater detail.

    Thanks for your answer.

    Well, I'm going to turn on the soldering iron then, as it seems to be the only practical solution.
