BQ24721CRHBT 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 layout will help reduce EMI and improve efficiency.
  • 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 that the inductor current ripple is within 20-40% of the average inductor current.
  • The maximum ambient temperature range for the BQ24721CRHBT is -40°C to 85°C. However, the device can operate at higher temperatures with derating. It's essential to ensure that the device is properly cooled to prevent overheating.
  • The BQ24721CRHBT has a built-in overcurrent protection feature. The OCP threshold can be set using an external resistor connected to the OCP pin. The device will shut down if the current exceeds the set threshold.
  • The BQ24721CRHBT is designed for battery-powered applications with input voltages up to 18V. For high-voltage applications, a different device or additional voltage regulation may be required. It's essential to ensure that the device is operated within its recommended voltage range.
