BQ25015RHLR Frequently Asked Questions (FAQs)

  • A good PCB layout is crucial for the BQ25015RHLR. TI recommends a 4-layer PCB with a solid ground plane, and the use of thermal vias to connect the thermal pad to the ground plane. Additionally, keep the input and output capacitors close to the IC, and use short, wide traces for the power paths.
  • To ensure stability, make sure to follow the recommended component values and PCB layout. Additionally, add a 10nF capacitor between the VCC pin and GND, and a 1uF capacitor between the VIN pin and GND. Also, ensure that the input and output capacitors are of high quality and have low ESR.
  • The BQ25015RHLR 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 BQ25015RHLR has a built-in voltage regulator that can be programmed using an external resistor divider network. The output voltage can be set between 0.9V and 5.5V by selecting the appropriate resistor values. Refer to the datasheet for the resistor calculation formula.
  • The BQ25015RHLR can deliver up to 1.5A of output current, but it's recommended to keep the output current below 1.2A to ensure reliable operation and to prevent overheating.
