Hi,

Can RESET_N pin of the PSpice model work in start-up transient simulation?

My customer simulated it, but RESET_N kept still low after Treset-act.

Hi, Sam-san

The customer used start-up profile of SNVMA59.ZIP which is uploaded on Ti.com. PLS check it.
The profile was run on ORCad 17.2 S062.

The customer will provide us the simulation result waveform later and I will share it with you.
Best Regards, Taki

Hi, Sam-san

The customer Customer used SNVMA58.ZIP, but not SNVMA59.ZIP.
LM53602 5p0V PSpice Transient Model

The schematic which the customer used and the waveform as the simulation result is attached. PLS see them.

Hi,

I run the simulation for the following PSpice Models, but RESET_N didn't work.

LM53602 3P3V PSpice Transient Model (SNVMA57.ZIP)
LM53602 5P0V PSpice Transient Model (SNVMA58.ZIP)

The signal works well in the following model.

LM53602 Adjustable PSpice Transient Model (SNVMA59.ZIP)

The customer want to simulate with SNVMA58.ZIP to use LM536025 for 5V output.
Could you check the both of model, SNVMA57.ZIP and SNVMA58.ZIP?

Best Regards, Taki
