BQ24703PWRG4 datasheet by Texas Instruments

BQ24703PWRG4 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow the layout guidelines in the application note 'BQ24703PWRG4 Layout Guidelines' (SLUAUH5) for optimal performance.
• How do I select the correct external components for the charger?
  The selection of external components such as resistors, capacitors, and inductors depends on the specific application and charging requirements. Refer to the datasheet and application notes for guidance on component selection. Additionally, Texas Instruments provides a 'Component Selection Guide' (SLUAUH4) to help with component selection.
• What is the maximum ambient temperature for reliable operation?
  The BQ24703PWRG4 is rated for operation up to 85°C ambient temperature. However, it's recommended to derate the device's performance and consider thermal management for reliable operation at high temperatures.
• How do I implement overvoltage protection (OVP) and undervoltage protection (UVP)?
  The BQ24703PWRG4 has built-in OVP and UVP features, but they can be adjusted or customized using external resistors and capacitors. Refer to the datasheet and application notes for implementation details.
• What is the recommended input capacitor type and value for the charger?
  A low-ESR ceramic capacitor or a film capacitor with a value of 10uF to 22uF is recommended for the input capacitor. The specific value depends on the input voltage and current requirements.
