I just discovered the LT application video on the SOAtherm-NMOS device. ?This looks like a really neat function. ?Searching the archives comes up with a thread from last year about converting datasheet information into SOAtherm models, but it looks like MatLab is needed. ?I'm not MatLab fluent (used it once, 20 years ago), but I'd like to model the FETs I'm using in my designs. ?Does anybody have any hints/tricks/recipes for determining the values of the entries in Dan Eddleman's DanTherm model? ?The library has these elements that determine the thermal model:
?
* The following two lines are customized for each DanTherm model *?
.param Tambient=85 RthetaJA=50 Cheatsink=0?
.param Imult=1.00E+01 Iexponent=3.00E-01 R6=3.18E-02 C6=1.77E-04 R5=1.01E-01 ?C5=2.77E-04 R4=2.74E-01 ?C4=1.60E-03 R3=8.49E-01 ?C3=8.83E-03 R2=7.34E-02 ?C2=3.30E-03 R1=1.05E-03 ?C1=1.82E-03
Do I need to contact Dan to get his modeling information?
Thanks,
Carl
