BQ2002TSNTR Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output capacitors close to the IC, and use short, wide traces for the power paths.
  • Consult the datasheet for the specific battery chemistry you are using, and adjust the charge voltage, charge current, and termination voltage accordingly. You may also need to adjust the charge timer and precharge timer.
  • Not using the thermistor input may prevent the BQ2002TSNTR from accurately monitoring battery temperature, which can lead to reduced charging performance, safety issues, or even damage to the battery.
  • Yes, but you will need to use an external balancing circuit to ensure each cell is charged and discharged evenly. The BQ2002TSNTR can only monitor and control a single cell.
  • Use a logic analyzer or oscilloscope to monitor the IC's control signals and voltage rails. Check for proper power supply decoupling, and ensure the input and output capacitors are properly sized and placed.
