FAN54015 Description
The FAN54015 bines 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 3.4 Mbps. The charger and boost regulator circuits switch at 3 MHz to minimize the size of external...
