BQ25101YFPR Frequently Asked Questions (FAQs)

  • TI recommends a compact layout with the IC placed close to the battery, and the input capacitors (CIN) placed as close as possible to the VIN pin. The output capacitors (COUT) should be placed close to the VOUT pin. A 4-layer PCB is recommended to minimize noise and EMI.
  • To minimize IQ, ensure the EN pin is driven high only when the converter is active. Use a low-leakage input capacitor (CIN) and a high-ESR output capacitor (COUT). Also, consider using a low-VIN, low-IQ LDO regulator for the VDD pin.
  • The BQ25101YFPR can handle input voltages up to 18V, but it's recommended to limit the input voltage to 15V to ensure reliable operation and minimize the risk of damage.
  • Ensure good thermal design and layout practices, such as using a thermal pad, thermal vias, and a heat sink if necessary. Also, consider using a thermistor or thermal sensor to monitor the temperature and implement thermal protection if needed.
  • A 10uF to 22uF X5R or X7R ceramic capacitor is recommended for CIN. The capacitor should be placed as close as possible to the VIN pin and have a low ESR to minimize input ripple and noise.
