   产品概述 返回TOPhqO嘉泰姆

The CXLB73117 is a complete battery charger controller for one (4.2V) cell lithium-ion battery.The CXLB73117 provides a small, simple and efficient solution to fast charge Li-ion battery. An external sense resistor sets the charge current with high accuracy. An internal resistor divider and precision reference set the final float voltage to 4.22V percell with 1% accuracy.When the input supply is removed, the CXLB73117 automatically enters a low current sleep mode,  dropping the battery drain current to 4μA. After the charge cycle ends, if the battery voltage drops below 4.05V per cell, a new charge cycle will automatically begin.

    The CXLB73117 is available in the 8-lead SO Package.   hqO嘉泰姆
