BQ24261MRGET Frequently Asked Questions (FAQs)

  • A good PCB layout for the BQ24261MRGET involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the high-current paths. TI provides a recommended layout in the datasheet and application notes.
  • The inductor value depends on the input voltage, output voltage, and maximum current. A good starting point is to use the inductor selection guide in the datasheet or TI's online inductor selection tool. You can also use the following formula: L (μH) = (Vin - Vout) / (ΔI * f * ΔIL).
  • The maximum ambient temperature for the BQ24261MRGET is 85°C. However, the device can operate up to 105°C with derating. It's essential to ensure proper thermal design and heat sinking to maintain a safe operating temperature.
  • The BQ24261MRGET has a built-in OVP feature that can be enabled by connecting the OVP pin to a voltage divider network. The OVP threshold is set by the voltage on the OVP pin, which should be set to 1.5V to 2.5V above the output voltage.
  • Yes, the BQ24261MRGET is qualified for automotive and high-reliability applications. It meets the AEC-Q100 standard and has been tested for robustness and reliability. However, it's essential to follow proper design and manufacturing guidelines to ensure the device meets the required standards.
