A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the high-current paths short and wide, and use thermal vias to dissipate heat.
Use a heat sink with a thermal resistance of 10°C/W or lower, and ensure good airflow around the device. Apply a thin layer of thermal interface material to the heat sink.
The maximum allowed voltage on the input pins is 24V, but it's recommended to keep it below 20V to ensure reliable operation.
The BQ29312APWR is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. Ensure proper thermal management and derate the device accordingly.
Use an oscilloscope to monitor the input and output voltages, and check for proper power sequencing. Verify that the input voltage is within the recommended range and that the device is properly thermally managed.
