BQ24045DSQR Frequently Asked Questions (FAQ)

  • A good PCB layout for the BQ24045DSQR 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, it's recommended to use a separate power plane for the input and output to minimize noise coupling.

  • The selection of external components such as the input and output capacitors, inductor, and resistors depends on the specific application requirements. TI provides a component selection guide in the datasheet, and engineers can also use TI's WEBENCH online design tool to simplify the component selection process.

  • The BQ24045DSQR has a maximum junction temperature of 125°C. To ensure reliable operation, engineers should ensure good thermal design, including a heat sink or thermal pad, and follow TI's recommended thermal design guidelines. Additionally, the device has built-in thermal protection, which will shut down the device if the junction temperature exceeds 150°C.

  • The BQ24045DSQR has a built-in overcurrent protection feature that can be enabled by connecting the OCP pin to a resistor divider network. The device will limit the output current to the programmed value, and if the current exceeds this value, the device will shut down. Engineers can also use external components to implement custom overcurrent protection schemes.

  • The BQ24045DSQR is designed to meet CISPR 22 Class B and FCC Part 15 Subpart B emissions standards. To ensure compliance, engineers should follow good PCB design practices, use shielding, and implement filtering and decoupling techniques. TI also provides EMI and EMC design guidelines in the datasheet and application notes.
