BQ24123RHLR Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output capacitors close to the IC, and use short, wide traces for the power paths. Avoid routing sensitive analog signals near the power paths.
  • Choose X5R or X7R ceramic capacitors with a voltage rating of at least 1.5 times the maximum input voltage. For the input capacitor, a value of 10uF to 22uF is recommended. For the output capacitor, a value of 22uF to 47uF is recommended. Ensure the capacitors are placed close to the IC and have a low ESR.
  • The BQ24123RHLR is rated for operation from -40°C to 85°C. However, the device may still function outside this range, but with reduced performance and reliability.
  • Yes, the BQ24123RHLR is suitable for battery-powered devices. It has a low quiescent current of 15uA, making it suitable for battery-powered applications. However, ensure the input voltage is within the recommended range and the device is properly configured for battery-powered operation.
  • The BQ24123RHLR has a fixed output voltage of 3.3V or 5V, depending on the version. However, you can use an external resistor divider network to adjust the output voltage. Refer to the datasheet for the recommended resistor values and configuration.
