一,产品概述(General Description) 
The CXLB7204 is a complete constant current/constant voltage linear charger
for cell lithium-ion batteries. Its package and low external component count make
the CXLB7204 ideally suited for portable applications. The charge current can be
programmed externally with a single resistor. CXLB7204 determines the charge
mode by detecting the battery voltage:Pre-charge, constant current charging,
constant voltage charging.The charge current of pre-charging and constant–
current charging is adjustable.
The CXLB7204 is monitored by temperature monitor during the constant
-current and constant-voltage charging. There are two LEDs indicate the charge
mode. The CXLB7204 is available in the SOP-8L package (or upon request).
