描述 Description

The SMB1352 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 a simple 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 SMB1352 high efficiency switch mode operation eliminates the low charge current and thermal problems of conventional solutions. The switching architecture in conjunction w....
