BQ24725RGRT 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 ground plane.
  • The inductor value depends on the input voltage, output voltage, and output current. A good starting point is to use the inductor value calculation formula provided in the datasheet. The inductor value should be selected to ensure that the inductor current ripple is within 20-30% of the output current.
  • A low-ESR ceramic capacitor with a value of 10-22uF is recommended. The capacitor should be placed close to the device and connected between the VIN pin and the GND pin.
  • The output voltage can be configured by connecting a resistor divider network between the VOUT pin and the GND pin. The resistor values can be calculated using the formula provided in the datasheet.
  • The maximum ambient temperature range for the BQ24725RGRT is -40°C to 85°C. However, the device can operate up to 125°C junction temperature.
