The CXLB7275 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 CXLB7275 ideally suited for portable applications. The charge current can be programmed externally with a single resistor, which may be programmed up to 1A. CXLB7275 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 CXLB7275is monitored by temperature monitor during the constant-current and constant-voltage charging. There are two LEDs indicate the charge mode. The CXLB7275is available in the SOP-8L package.
