BQ25890RTWT Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate layer for the power traces is recommended. Keep the input and output capacitors close to the IC, and use a Kelvin connection for the sense resistors.
  • Use the TI WEBENCH Power Designer tool to generate a compensation network based on the specific application requirements. The tool provides a recommended compensation network based on the input and output voltage, output current, and other parameters.
  • The BQ25890RTWT can handle up to 18V input voltage, but it's recommended to keep the input voltage below 15V to ensure reliable operation and to prevent damage to the IC.
  • Monitor the junction temperature (TJ) of the IC, which should not exceed 125°C. Use thermal design and layout techniques, such as thermal vias and heat sinks, to reduce the thermal resistance and keep the IC within its thermal limits.
  • A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended for the input capacitor. The capacitor should be rated for the maximum input voltage and have a low equivalent series resistance (ESR) to minimize voltage ripple and ensure stable operation.
