10 Power Supply Recommendations

A power supply capable of providing VCC between 4.35 V and 16 V and at least 100 mA up to 2 A is required for the IC to operate. For the battery to fully charge, the power supply must be capable of providing at least VO(BAT-REG) + V(BATDO). As the input voltage increases, the IC's power dissipation increases. The thermal protection loop of the IC, as explained in Temperature Regulation and Thermal Protection, reduces the input current current from the maximum (2 A when MODE = H and either 100 mA or 500 mA per ISET2 if MODE = L) to prevent damage to the IC.
