BQ25890RTWR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the datasheet, but it's essential to follow good PCB design practices, such as keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing trace lengths and widths to reduce EMI.
  • The inductor value depends on the input voltage, output voltage, and desired output current. A good starting point is to use the inductor selection guide in the datasheet, and then fine-tune the value based on the specific application requirements.
  • The BQ25890RTWR is rated for operation from -40°C to 125°C, but the maximum ambient temperature range depends on the specific application and the thermal design of the system. It's essential to ensure proper thermal management to prevent overheating.
  • The BQ25890RTWR has a built-in overcurrent protection feature that can be enabled by connecting the OCP pin to a resistor divider network. The datasheet provides a detailed explanation of how to implement overcurrent protection, including the calculation of the resistor values.
  • The BQ25890RTWR is rated for input voltages up to 18V, but it's not recommended for high-voltage applications above 18V. If you need to support higher input voltages, consider using a different device or adding external voltage regulation.
