BQ24155RGYR Frequently Asked Questions (FAQs)

  • A good PCB layout for the BQ24155RGYR involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the traces between the device and the capacitors. TI provides a recommended PCB layout in the datasheet and application notes.
  • The selection of input and output capacitors for the BQ24155RGYR depends on the specific application requirements. TI recommends using low-ESR capacitors with a minimum capacitance of 10uF for the input and output. The capacitor selection guide in the datasheet provides more information.
  • The BQ24155RGYR can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V for optimal performance and to prevent overheating.
  • The BQ24155RGYR output voltage can be configured using the EN/DVS and FB pins. The EN/DVS pin sets the output voltage to either 3.3V or 5V, and the FB pin allows for adjustable output voltage using a resistive divider network. The datasheet provides more information on the configuration options.
  • The BQ24155RGYR has a thermal shutdown feature that turns off the device when the junction temperature exceeds 150°C. To prevent overheating, it's recommended to provide adequate airflow, use a heat sink if necessary, and ensure good thermal conductivity between the device and the PCB.
