Hi,

I am interested in the device indicated in the title.
I would like to check its dynamic operation by PSPICE-FOR-TI etc. if possible.

Does a SPICE macro model exist?

Hello Tamura,

The BQ25750 does not have a PSPICE model. We do have the BQ25750EVM available for testing though.

Let me know if you have any questions about this.

Best Regards,
Ethan Galloway

Dear, Ethan Galloway.

Thank you for your answer.
I am sorry, but I have one more question.

I understand that the BQ25756 design calculator can be substituted for the BQ25750 at the following URL.
Other than checking the design calculator, please let us know if there are any other items that need to be calculated and verified by reading the datasheet.

Dear Tamura,

The BQ25756 and BQ25750 are very similar ICs. I'd recommend checking and verifying that your ICHG, IAC_DPM, ACUV, ACOV, and system load work together.

Just for reference, here is the BQ2575X FAQ page: https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1357460/faq-bq2575x-central-faq-page

You can also find the BQ25750 schematic and layout checklist in the link as well.
