描述 Description

The SMB1350/SMB1351 device is a programmable single-cell lithium-ion (Li-ion)/lithium-polymer (Li-Polymer) battery charger designed for a variety of portable applications. The device provides asimple and efficient way to charge high-capacity Li-ion batteries and power the system via a universal serial bus (USB) or AC adapter input. Unlike conventional charging devices, the SMB1350/SMB1351 high efficiency switch mode operation eliminates the low charge current and thermal problems of conventional solutions. The switching architecture....
