.. . Interesting First Cut at Spice Modeling of TLP191B... http://www.analog-innovations.com/SED/TLP191B_2014-04-06.pdf Tanh very useful. However... I haven't run your model, but it looks like you have omitted input diode modelling. The clue is that I don't see any Diode model with N !=1 I did this model for a H11FXM opto a while back.

I hacked an LT Spice library part to sim the Avago coupler with variable CTR. It matches the hardware behavior pretty well. https://dl.dropboxusercontent.com/u/..._Input_Sim.jpg That particular run is a sweep to determine the voltage threshold. -- John Larkin Highland Technology, Inc jlarkin att highlandtechnology dott com http://www.highlandtechnology.com |
