BQ24113ARHLR Frequently Asked Questions (FAQ)

  • The recommended layout and placement for the BQ24113ARHLR 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. The datasheet provides a recommended layout and placement diagram.

  • To optimize the charging current for your specific battery, you need to consider the battery's chemistry, capacity, and recommended charging current. The BQ24113ARHLR has a programmable charging current, and you can adjust the ICHG pin to set the charging current. You can also use the device's built-in battery detection feature to detect the battery type and adjust the charging current accordingly.

  • The BQ24113ARHLR has a thermal shutdown feature that turns off the device when the junction temperature exceeds 150°C. To ensure reliable operation, it's essential to provide adequate thermal relief, such as a heat sink or a thermal pad, and to follow the recommended PCB layout and placement guidelines.

  • The BQ24113ARHLR has a built-in overvoltage protection (OVP) feature that turns off the device when the input voltage exceeds 6.5V. You can also implement external OVP using a voltage supervisor or a Zener diode to protect the device from high input voltages.

  • To minimize electromagnetic interference (EMI) and ensure electromagnetic compatibility (EMC), it's essential to follow proper PCB layout and placement guidelines, use a shielded cable for the USB connection, and add EMI filters or ferrite beads to the input and output lines.
