BQ25890HRTWR Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate layer for the high-current paths is recommended. The datasheet provides a recommended layout, but it's essential to follow good PCB design practices to minimize noise and EMI.
  • Choose an inductor with a high saturation current rating, low DCR, and a suitable inductance value (e.g., 1-2.2 μH). Consider the inductor's physical size, core material, and temperature rating. TI provides a list of recommended inductors in the datasheet.
  • The BQ25890HRTWR can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V to ensure reliable operation and minimize power losses.
  • Use the FB pin to set the output voltage. Connect a resistive divider from the output voltage to the FB pin, and calculate the resistor values using the datasheet's equations. You can also use TI's WEBENCH tool to simplify the design process.
  • The EN (enable) pin is used to turn the converter on and off. Connect the EN pin to a logic signal (e.g., from a microcontroller) to enable or disable the converter. When EN is low, the converter is in shutdown mode, reducing quiescent current.
