LM3880: Sequencers Forum

Part Number: LM3880

Hello,

I have a question regarding the LM3880 PSpice model from TI.

So far, I have been able to downloaded the associated SPICE model, open and view the model, and place the LM3880 part into PSpice. I can run a PSpice simulation without errors. 

My problem is: 

The flag voltages stay at 0 Volts. I first apply Vcc = 6V followed by applying EN = 3.3V. FLAG 1,2,3 all stay low at 0V. No sequencing or any kind of operation is apparent.

How can I get this models working?

I've attached some pictures to help illustrate my issue.

Thanks
