BQ24753ARHDT 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 good thermal design is also crucial to ensure the device operates within its thermal limits.
  • The inductor value depends on the input voltage, output voltage, and switching frequency. A good starting point is to use the inductor value calculation formula provided in the datasheet. The inductor value should be chosen to ensure the desired output voltage ripple and to prevent inductor saturation.
  • A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended. The capacitor should be placed close to the device and should be rated for the input voltage and operating temperature range.
  • The device should be mounted on a PCB with a good thermal design, and a heat sink may be required depending on the operating conditions. The device's thermal pad should be connected to a solid ground plane to ensure good heat dissipation. The device's junction temperature should be monitored to ensure it operates within its specified range.
  • The EN pin is an active-high enable input that allows the device to be turned on and off. When the EN pin is high, the device is enabled, and when it is low, the device is disabled. The EN pin can be connected to a logic signal or a switch to control the device's operation.
