The FAN54005UCX from On Semiconductor is a versatile, highly integrated switch-mode charger designed for single-cell Li-Ion and Li-Polymer battery packs. It is configurable for systems requiring charge currents ranging from 200 mA to 1.45 A, utilizing a single external resistor for setup.
This device offers advanced charging control through a high-speed I2C interface, allowing programmability of input current, fast-charge/termination current, charger voltage, and termination enable. The charger and boost regulator circuits operate at 3 MHz to minimize external passive component size. Key electrical specifications include a charge voltage accuracy of ±0.5% at 25°C and ±1% from 0 to 125°C, with ±5% accuracy for input current and charge current regulation.
The FAN54005UCX also functions as a 5V, 500mA boost regulator for USB On-The-Go (OTG) applications, using the same external components as the charging circuit. It operates within a supply voltage of up to 6V and an ambient temperature range of -30°C to 85°C. The device is housed in a compact 20-WLCSP (20-UFBGA, WLCSP) package, suitable for space-constrained designs.
Applications for the FAN54005UCX include wireless speakers, headphones, cell phones, gaming devices, toys, drones, digital cameras, IoT devices, and e-cigarettes.
