The CXLB7399 is a complete constant-current/constant voltage linear charger for cell lithium-ion batteries. Its package and low external component count make the CXLB7399 ideally suited for portable applications。The charge current can be programmed externally with a single resistor.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 CXLB7399 is monitored by temperature monitor during the constant-current and constant-voltage charging. There are two LEDs indicate the charge mode.The CXLB7399 is available in the SOP-8L package (or upon request).
