TCA9509: TCA9509 Simulation model request

user6063109

Part Number: TCA9509

I'd like to simulate the I2C waveform of TCA9509 for selecting appropreate pull-up resister.

I already installed PSpice for TI and serached TCA9509 model, but I couldn't find it.

Could you please provide the model or suggest an alternative simulation method?

Hi User6063109,

I will need more time to answer your question.

Hi User6063109,

There is not TCA9509 PSPICE or TI model for simulation purposes.

There is an IBIS model for TCA9509,

Hi Tyler,

I understand that you provide us only IBIS model, and I will try to simulate by this IBIS model.

Thank you for your prompt reply and support.

Hi Tyler,

I could simulate I2C waveform from IBIS model on PSpice for TI.

And I used these models for 1.8V > 3.3V level shiifter waveform.

TCA9509_RVHJNA_18_TYP
TCA9509_RVHJNA_33_TYP

Thank you for your support.
