11 Power Supply Recommendations

The devices are designed to operate from an input voltage range between 4.35V and 10.5V. This input supply must be well regulated. If the input supply is located more than a few inches from the bq24250 charger, additional bulk capacitance may be required in addition to the ceramic bypass capacitors.
