BQ24707ARGRT Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. The device should be placed near the battery, and the power inductors should be placed close to the device. A thermal pad should be used to connect the device to the PCB.
  • The inductor value depends on the input voltage, output voltage, and output current. A good starting point is to use the inductor value recommended in the datasheet. Then, adjust the value based on the specific application requirements and efficiency targets.
  • The maximum ambient temperature for the BQ24707ARGRT is 85°C. However, the device can operate at higher temperatures with derating. Consult the datasheet for more information on temperature derating.
  • The BQ24707ARGRT has a built-in overcurrent protection feature. The OCP threshold can be set using an external resistor. The device will limit the output current to the set threshold during an overcurrent event.
  • Yes, the BQ24707ARGRT is designed to operate in high-vibration environments. However, it's essential to ensure that the PCB is properly secured and the device is properly soldered to the PCB to prevent mechanical stress.
