BQ24161BRGET Frequently Asked Questions (FAQs)

  • The recommended layout and placement for the BQ24161BRGET involves placing the device close to the battery, using a solid ground plane, and keeping the input and output capacitors close to the device. Additionally, the device should be placed away from high-current carrying traces and heat sources.
  • To optimize the charging current for your specific battery, you can adjust the resistor values of R_ILIM and R_ISET to set the charging current. You can also use the EN pin to dynamically adjust the charging current based on the battery's state of charge.
  • The BQ24161BRGET has a thermal shutdown feature that turns off the device when the junction temperature exceeds 150°C. To minimize thermal issues, ensure good airflow, use a heat sink if necessary, and avoid blocking the thermal pad on the bottom of the device.
  • The BQ24161BRGET has a built-in OVP feature that can be enabled by connecting the OVP pin to a voltage source. You can also use an external OVP circuit with a zener diode and a resistor to provide additional protection.
  • While the BQ24161BRGET is optimized for Li-ion batteries, it can be used with other battery chemistries with some modifications. However, you may need to adjust the charging voltage and current profiles, and ensure that the device's protection features are compatible with the battery chemistry.
