The BQ25190 Small Form Factor schematic are shown in Figure 2-1. The components are the required components for operation and included in the 30mm² solution size for the charger.

Components outside of this section are not essential for operation but are included for end user interaction and configuration of the default V_buck setting. In a final application, the GPIO resistors can be directly shorted to GND or SYS for configuration without adding to the bill of materials or solution size. Included in this design are also the TS resistor, I²C Pull-ups, a push-button, and a USB2ANY interface. These components are found on other parts of the application, shared with other components, or directly present on a battery pack.
