LM5069: LM5069-2 Unencrypted PSpice Transient Model Package (Rev. A) - parameters?

Thomas Lechner
Prodigy 30 points
Part Number: LM5069

Hello,

within LM5069-2_trans.lib (and also in -1_trans.lib), I can find 2 parameters: "+ PARAMS: Rsense = 0.008 Rpwr = 56k"

Why is there a need for those parameters? The shunt resistor and the other resistor should be external resistors which are not part of the IC.  ( I am actually trying to simulate a hot swap condition using LM5069).

BR,

Thomas Lechner

    Hi Thomas Lechner,

    Welcome to E2E!

    Those components values are treated as parameters for calculating the power limit and current limit thresholds internally. Those gets updated when you change in the schematic and run the simulation.
