BQ24780SRUYT Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate layer for the high-current paths is recommended. Ensure that the input and output capacitors are placed close to the IC, and the high-current paths are routed away from sensitive analog signals.
  • Use the TI's WEBENCH Power Designer tool to generate a customized compensation network based on your specific application requirements. You can also refer to the application note SLUA623 for guidance on manual compensation design.
  • The maximum input voltage rating is 24V, but it's recommended to operate within 18V to ensure reliable operation and minimize the risk of damage.
  • The BQ24780SRUYT is rated for operation up to 105°C, but it's essential to ensure proper thermal management and heat sinking to prevent overheating. Use thermal interface materials and follow the recommended layout guidelines to minimize thermal resistance.
  • The BQ24780SRUYT has a built-in overcurrent protection feature. Connect a sense resistor (Rs) between the VIN and GND pins, and set the overcurrent threshold (Ilim) using the ILIM pin. The IC will automatically limit the output current when the sense voltage exceeds the threshold.
