Hi, TI Support Team

Is there no EVM for BQ25890H?

Not found on ti.com.

If you have the PCB LAY-OUT GUIDE of BQ25890H, please share.

I would like to receive a GUIDE up to the external PATTERN design part.

Please share the data.

Thanks.

Hi MJ,

Please visit https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/874557/faq-bq25890-faq-bq2589x-schematic-review-and-pcb-layout-design-tips for BQ2589X: Schematic Review and PCB Layout Design Tips. The BQ25890H is similar to the BQ25890.

The one difference with the BQ25890H compared to the BQ25890 is the implementation of DSEL digital output pin (pin 24 on attached schematic). You can look at the BQ25890 EVM here: https://www.ti.com/tool/BQ25890EVM-664

Additionally, see Section 11 in the BQ25890H datasheet for additional layout guidelines. These guidelines are the same as the BQ25890.

Regards,

James
