   产品概述 返回TOPKQg嘉泰姆

The CXLB7257C is a complete battery charger controller for one (4.22V) cell lithium-ion battery. The CXLB7257C 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 per cell with ±1% accuracy. When the input supply is removed, the CXLB7257C 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 CXLB7257C is available in the SOP8/PP package。</h2>
