BQ294703DSGT 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 'BQ294703 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 (BQ294703 Sense Resistor Calculator) that can help you select the correct value. Additionally, the datasheet provides guidelines for selecting 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 BQ294703 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 example of how to implement OVP, and TI also provides an application note 'Overvoltage Protection with the BQ294703' (SLUAUH6) that provides more information.
  • The BQ294703 is a high-power device, and thermal management is critical to ensure reliable operation. TI recommends using a thermal pad or heat sink to dissipate heat, and the datasheet provides thermal resistance values to help with thermal design. Additionally, the application note 'Thermal Management with the BQ294703' (SLUAUH5) provides more information on thermal management strategies.
