BQ294707DSGT 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 'BQ29470x 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 (BQ29470 Sense Resistor Calculator) that can help you select the correct value. Additionally, the datasheet provides a formula to calculate the sense resistor value.
  • The maximum voltage rating for the input capacitor is not explicitly stated in the datasheet, but it's recommended to use a capacitor with a voltage rating of at least 1.5 times the maximum input voltage to ensure reliable operation.
  • The BQ294707DSGT has a built-in OVP feature that can be enabled by connecting the OVP pin to a voltage divider network. The datasheet provides a detailed description of the OVP implementation, and TI also provides an application note 'Overvoltage Protection with the BQ29470' (SLUAUH6) for more information.
  • The thermal derating for the BQ294707DSGT is not explicitly stated in the datasheet, but it's recommended to follow the thermal derating guidelines provided in the TI application note 'Thermal Derating Guidelines for Texas Instruments Linear and Switching Regulators' (SLUAAC4).
