BQ7790502PWR Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the power traces short and wide, and use a common ground point for the device.
  • Use a high-precision voltage reference, ensure accurate resistor values for the voltage divider, and calibrate the device during manufacturing or at the point of use.
  • The maximum allowed voltage on the SENSE pin is 4.5V. Exceeding this voltage may damage the device.
  • Yes, but the device's accuracy and performance may vary depending on the battery chemistry. Consult the datasheet and application notes for guidance on using the device with other battery chemistries.
  • The POR and BOR features are enabled by default. Ensure that the power supply is stable and within the recommended operating range to avoid unwanted resets.
