.. . 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. Matches DC curves very well. ..SUBCKT h11fxm_XN 1 2 3 4 * B1 3 4 i=0.04*tanh(20*V(3,4))*I(V1) D1 1 5 DMod V1 5 2 DC 0 c1 3 4 10p c2 1 3 0.2p c3 2 4 0.2p ..model DMod D(is=1p Rs=3 CJO=50p Tt=10n Bv=50 Ibv=0 N=2.15) ..ENDS http://www.kevinaylward.co.uk/ee/misc/H11FXM.png Kevin Aylward B.Sc. www.anasoft.co.uk SuperSpice |

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 |
