BQ25070DQCT Frequently Asked Questions (FAQs)

  • A good PCB layout for the BQ25070DQCT involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the traces between the IC and the capacitors. TI provides a recommended PCB layout in the datasheet and application notes.
  • The choice of input and output capacitors depends on the specific application and requirements. Generally, X5R or X7R ceramic capacitors with a voltage rating of 10V or higher are recommended. The capacitance value should be at least 10uF for the input capacitor and 22uF for the output capacitor.
  • The BQ25070DQCT can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V to ensure reliable operation and to prevent overheating.
  • The BQ25070DQCT has a built-in OVP feature that can be enabled by connecting the OVP pin to a voltage divider network. The OVP threshold can be set by adjusting the voltage divider ratio.
  • The BQ25070DQCT is rated for operation up to 85°C, but it can be derated for higher temperatures. However, it's recommended to keep the junction temperature below 125°C to ensure reliable operation and to prevent overheating.
