BQ24052DSQT Frequently Asked Questions (FAQs)

  • The recommended layout and placement for the BQ24052DSQT involves placing the device close to the battery, using a solid ground plane, and keeping the input and output capacitors close to the device. A 4-layer PCB with a solid ground plane is recommended. Refer to the TI application note SLUA623 for more details.
  • The charging current can be optimized by selecting the appropriate resistor values for the ISET pin. The ISET pin sets the charging current, and the recommended values are provided in the datasheet. Additionally, the charging current can be adjusted based on the battery's capacity and chemistry.
  • The BQ24052DSQT 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. Refer to the datasheet for thermal resistance values.
  • The BQ24052DSQT has a built-in OVP feature that can be enabled by connecting the OVP pin to a voltage divider network. The OVP threshold is set by the voltage divider ratio, and the recommended values are provided in the datasheet.
  • The BQ24052DSQT is designed for Li-Ion/Li-Polymer batteries, but it can be used with other chemistries with some modifications. However, the charging algorithm and voltage thresholds may need to be adjusted. Consult the datasheet and TI application notes for more information.
