BQ25101YFPT Frequently Asked Questions (FAQs)

  • Texas Instruments 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 with a solid ground plane is recommended to minimize noise and EMI.
  • To minimize IQ, ensure that the EN pin is driven high only when the converter is active. Use a low-leakage input capacitor (CIN) and a low-ESR output capacitor (COUT). Additionally, optimize the inductor selection to minimize core losses. Finally, consider using a low-VIN, low-VOUT configuration to reduce IQ.
  • The BQ25101YFPT 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 conduction between the IC and the PCB. Use a thermal pad or a heat sink to dissipate heat. Monitor the junction temperature (TJ) and adjust the operating conditions to keep TJ below 125°C. Reduce the output current or increase the airflow to prevent overheating.
  • A low-ESR, X5R or X7R ceramic capacitor with a value between 4.7μF and 10μF is recommended for the input capacitor (CIN). This helps to filter the input voltage and reduce noise.
