A 4-layer PCB with a solid ground plane and a separate layer for the power traces is recommended. The datasheet provides a recommended PCB layout, but it's essential to follow good PCB design practices to minimize noise and ensure optimal performance.
The inductor selection depends on the input voltage, output voltage, and output current. A good starting point is to use the inductor selection guide provided in the datasheet. Additionally, consider the inductor's saturation current, DC resistance, and core material to ensure it can handle the required current and minimize losses.
The BQ25616JRTWT can handle input voltages up to 18V, but it's recommended to operate within the specified input voltage range (4.5V to 14V) for optimal performance and to prevent damage to the device.
The BQ25616JRTWT has a programmable charging profile using the I2C interface. Use the TI-provided software tools or consult the datasheet to configure the charging profile, including the charge voltage, charge current, and termination voltage.
The BQ25616JRTWT has a thermal shutdown feature that protects the device from overheating. Ensure good thermal design practices, such as providing adequate airflow, using thermal vias, and selecting a suitable thermal interface material to keep the device within its operating temperature range (-40°C to 85°C).
