LM74930-Q1: Load dump test pulse ISO 16750-2 simulation in TINA-TI

Part Number: LM74930-Q1
Other Parts Discussed in Thread: TINA-TI,

Tool/software:

Hello,

I'm trying to simulate the unsuppressed and suppressed load dump test pulse from ISO 16750-2 for 24V system.

In another thread (LM7480-Q1: Simulation of ISO-7637 or ISO-16750 pulse) there was a piecewise linear definition provided, however I need a more accurate model. Especially the phase after reaching Us voltage and falling to 0,1*(Us-Ua)+Ua is too inaccurate for my purpose in this model, because it is modelled purely linear.

Has an improved model become available in the meantime? Either piecewise linear or even a wave file?

Best regards, Oliver.
