BQ24091DGQR Frequently Asked Questions (FAQs)

  • A good PCB layout for the BQ24091DGQR involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the traces between the device and the capacitors. TI provides a recommended PCB layout in the datasheet and application notes.
  • The selection of external components such as capacitors, resistors, and inductors depends on the specific application requirements. TI provides guidelines for component selection in the datasheet and application notes. Additionally, TI's WEBENCH online design tool can be used to select components and simulate the design.
  • The BQ24091DGQR can handle input voltages up to 18V, but it's recommended to operate within the specified input voltage range of 4.5V to 16V for optimal performance and reliability.
  • The BQ24091DGQR has a built-in overcurrent protection feature that can be enabled by connecting a sense resistor to the OCP pin. The device will limit the output current to the programmed value when an overcurrent condition is detected.
  • The BQ24091DGQR is rated for operation up to 105°C, but the device's performance and reliability may degrade at high temperatures. It's recommended to follow the thermal design guidelines in the datasheet and application notes to ensure reliable operation in high-temperature environments.
