产品概述 返回TOP
The CXLB7277 is a complete battery charger controller for two (8.4V) cells lithium-ion batteries. The CXLB7277 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 8.4V. When the input supply is removed, the CXLB7277 automatically enters a low current sleep mode. The CXLB7277 is available in the SOP-8L package.
