BQ29737DSER Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the high-current paths short and wide, and use thermal vias to dissipate heat.
  • Use a low-impedance voltage sense line, keep the sense lines short, and avoid routing them near high-current paths. Also, ensure the sense lines are properly filtered and shielded.
  • The maximum allowed voltage drop is 100 mV. Exceeding this may affect the accuracy of the voltage sensing and charging control.
  • Yes, but you may need to adjust the charging parameters and voltage thresholds according to the specific battery chemistry. Consult the datasheet and application notes for guidance.
  • Use the OVP pin to detect overcharge conditions. When OVP is triggered, the device will terminate charging and enter a safe state. You can also use external circuitry to enhance overcharge protection.
