BQ24253RGET Frequently Asked Questions (FAQs)

  • A good PCB layout for the BQ24253RGET involves placing the input capacitors close to the VIN pin, using a solid ground plane, and keeping the high-current paths short and wide. A 4-layer PCB with a dedicated power plane is recommended.
  • 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, and then fine-tune the value based on the specific application requirements.
  • The BQ24253RGET is rated for operation from -40°C to 85°C. However, the device can be operated at higher temperatures with derating, but this may affect its reliability and lifespan.
  • Yes, the BQ24253RGET is suitable for battery-powered applications. It has a low quiescent current and can operate from a single-cell Li-ion battery. However, the device's power-save mode should be used to minimize power consumption when the battery is not charging.
  • The BQ24253RGET has a built-in OVP feature that can be enabled by connecting the OVP pin to a voltage divider network. The OVP threshold can be set by selecting the appropriate resistor values in the voltage divider.
