BQ24120RHLT Frequently Asked Questions (FAQs)

  • The recommended layout and placement for the BQ24120RHLT 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. TI provides a reference layout in the datasheet.
  • The BQ24120RHLT has a programmable charging current and voltage. To optimize these settings for your specific battery, refer to the battery manufacturer's recommendations and adjust the charging current and voltage accordingly using the I2C interface or external resistors.
  • The BQ24120RHLT is rated for operation from -40°C to 85°C. However, the device can be derated for higher temperatures. Consult the datasheet for thermal derating information.
  • The BQ24120RHLT has built-in OVP and OCP. For OVP, the device will automatically disconnect the input when the input voltage exceeds 6.5V. For OCP, the device will limit the charging current to prevent damage. You can also adjust the OCP threshold using external resistors.
  • The BQ24120RHLT is designed for Li-Ion/Li-Polymer batteries. However, with proper configuration and external circuitry, it can be used with other battery chemistries. Consult the datasheet and application notes for guidance on using the device with non-standard battery chemistries.
