Design Notes
Place the input and output capacitors as close as possible to the VCC and BAT pins to minimize parasitic inductance. Use a 10uF ceramic capacitor for input and a 10uF ceramic capacitor for output. The sense resistor should be placed near the SRP and SRN pins to reduce noise pickup. Ensure the exposed pad is soldered to a large copper area for thermal dissipation.
The BQ24610RGER can dissipate significant power at high charge currents. The VQFN package has a thermal resistance of approximately 30Β°C/W. For 10A charging, ensure adequate PCB copper area and thermal vias to keep the junction temperature below 125Β°C. Consider using a heatsink or forced airflow in high-ambient-temperature environments.
Do not exceed the absolute maximum input voltage of 28V. Ensure the adapter current limit is set correctly to avoid overloading the adapter. The charge voltage set resistor must be accurate to maintain the Β±0.5% regulation. Also, verify the battery temperature sense (TS) pin is connected to a proper thermistor to prevent charging in extreme temperatures.
