BQ294704DSGT Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow the guidelines in the application note 'BQ294704 PCB Layout Guidelines' (SLUAUH7) for optimal performance.
  • The sense resistor value depends on the maximum current and voltage of your application. TI provides a sense resistor calculator tool (SLVCAT) that can help you select the correct value. You can also refer to the application note 'BQ294704 Sense Resistor Selection' (SLUAUH6) for more information.
  • The BQ294704DSGT has a maximum voltage rating of 36V, but it's recommended to operate the device within the recommended operating conditions specified in the datasheet to ensure reliable operation.
  • The BQ294704 has a built-in overcurrent protection feature that can be enabled by connecting the OCP pin to a resistor divider network. The application note 'BQ294704 Overcurrent Protection' (SLUAUH5) provides more information on how to implement overcurrent protection.
  • The typical response time for the OVP feature is around 1us, but this can vary depending on the specific application and PCB layout. It's recommended to verify the response time in your specific application.
