BQ2205LYPW Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a compact layout with the BQ2205LYPW placed close to the battery, and the input capacitors (CIN) placed as close as possible to the device. The output capacitors (COUT) should be placed close to the load.
  • To minimize IQ, ensure the EN pin is driven from a low-impedance source, use a low-value resistor (e.g., 1 kΩ) between the EN pin and the input voltage, and minimize the voltage drop across the input capacitor (CIN).
  • The maximum input voltage rating for the BQ2205LYPW is 6.5V. Exceeding this voltage may damage the device.
  • Ensure good thermal conductivity between the device and the PCB, use a thermal pad or thermal via, and consider using a heat sink or thermal interface material to reduce thermal resistance.
  • A 10 μF to 22 μF ceramic capacitor (X5R or X7R dielectric) is recommended for the input capacitor (CIN). The capacitor should be placed as close as possible to the device.
