Test Plan Development Guide
Thought for 1 min 16 sec
The project description has been updated to reflect a single-cell power bank design with a 30,000 mAh capacity, a USB-C output of 5V/3A, and the inclusion of a fuel gauge for accurate battery level monitoring.

List the recommended decoupling capacitors for the BQ25895 and add them to my schematic.
Thought for 1 min 11 sec
The BQ25895 datasheet recommends the following decoupling strategy:
-
High-Frequency Decoupling:
Use one 100nF ceramic capacitor (typically in a 0402 package) placed as close as possible to the VBUS (and/or SYS) pin to filter high-frequency noise. For example, you can use the 100nF 0402 capacitor. -
Bulk Decoupling:
In addition, a 10µF capacitor (typically in a 0603 package) is recommended to provide bulk decoupling for stability under load transients. An option is the 10uF 0603 Capacitor.
I will add these decoupling capacitors to your schematic near the appropriate nodes of the BQ25895: one 100nF capacitor for high-frequency bypassing at the VBUS pin and one 10µF capacitor for bulk decoupling at the supply input.
