PSC5425 USB-Compliant Single-Cell Li-lon Switching Charger with USB-OTG Boost Regulator Description The PSC5425 combines a highly integrated switch-mode charger, to minimize single-cell Lithium-ion (Li-ion) charging time from a USB power source, and a boost regulator to power a USB peripheral from the battery. The charging parameters and operating modes are programmable through an I2C interface that operates up to 400kbps. The charger circuits switch at 1.5MHz to minimize the size of external passive components. The PSC5425 provides battery charging in three phases: conditioning, constant current, and constant voltage. To ensure USB compliance and minimize charging time, the input current is limited to the value set through the I2C host.
