BQ25504: System Simulation for BQ25504 Followed by TPS63900

Part Number: BQ25504
Other Parts Discussed in Thread: TINA-TI, TPS63900

Hi There,

I am building an energy harvesting system that uses BQ25504 as a first stage followed by TPS63900. I am unable simulate the systems since the BQ25504 only has model files in TINA-TI and the TPS63900 has model files for PSpice only. Will it be possible to simulate the system in one platform (TINA or PSpice).

Thanks,

Mahmoud

Hi Mahmoud,

We no longer support the BQ25504 TINA model. By googling how to convert TINA spice model to pspice, I found the following:

There were also options to go from pSpice to TINA.

Hi Jeff,

Both models are encrypted for their respective simulator (BQ25504 for TINA-TI and TPS63900 for PSpice). The videos you mentioned are for unencrypted model files. Are there instruction for importing encrypted model files from one platform to another?

Thanks,

Mahmoud
