BQ24103RHLR Frequently Asked Questions (FAQs)

  • A good PCB layout for the BQ24103RHLR involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the traces between the IC and the capacitors. TI provides a recommended layout in the datasheet and application notes.
  • The selection of input and output capacitors depends on the specific application requirements. Generally, X5R or X7R ceramic capacitors with a voltage rating of 10V or higher are recommended. The capacitance value should be at least 4.7uF for the input capacitor and 10uF for the output capacitor.
  • The BQ24103RHLR can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V to ensure reliable operation and to prevent overheating.
  • The BQ24103RHLR has a built-in OVP feature that can be enabled by connecting the OVP pin to a voltage divider network. The OVP threshold can be set by selecting the appropriate resistor values in the voltage divider network.
  • The BQ24103RHLR is rated for operation up to 85°C, but it's recommended to derate the output current and input voltage at higher temperatures to ensure reliable operation. TI provides thermal derating curves in the datasheet.
