BQ24040DSQT Frequently Asked Questions (FAQs)

  • A good PCB layout for the BQ24040DSQT involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the traces between the device and the capacitors. TI provides a recommended PCB layout in the datasheet and application notes.
  • The selection of input and output capacitors for the BQ24040DSQT depends on the specific application requirements. Generally, X5R or X7R ceramic capacitors with a voltage rating of 10V or higher are recommended. The capacitance value should be at least 4.7uF for the input capacitor and 10uF for the output capacitor.
  • The BQ24040DSQT can handle input voltages up to 18V, but it is recommended to operate within the specified input voltage range of 4.5V to 12V for optimal performance and reliability.
  • The BQ24040DSQT 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 selecting the appropriate resistor values in the voltage divider network.
  • The BQ24040DSQT is rated for operation up to 85°C, but it can be derated for higher temperatures. However, it is recommended to consult the datasheet and application notes for specific guidance on operating the device in high-temperature environments.
