一,产品概述(General Description)      

   The CXLB7269-NG is a highly advanced complete constant-current/ constant
voltage linear charger for cell lithium-ion batteries. Its package and low external
component count make the CXLB7269-NG ideally suited for portable applications.
The charge current can be programmed externally with a single resistor, which may
be programmed up to 1A. CXLB7269-NG determines the charge mode by detecting
the battery voltage:Pre-charge, constant current charging, constant voltage charging.
The charge current of 0pre-charging and constant –current charging is adjustable.
The CXLB7269-NG is monitored by temperature monitor during the constant-current
and constant-voltage charging. There are two LEDs indicate the charge mode.
The CXLB7269-NG is available in the SOP-8L package.
