In most applications, all that is needed is a high-frequency decoupling capacitor. A 0.1-µF ceramic, placed in proximity to VCC and VSS pins, works well. The BQ2057 works with both regulated and unregulated external dc supplies. If a nonregulated supply is chosen, the supply unit should have enough capacitance to hold up the supply voltage to the minimum required input voltage at maximum load. If not, more capacitance must be added to the input of the charger.
