The HX6028 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 HX6028 ideally suited for portable applications. The charge current can be programmed externally with a single resistor. HX6028 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 HX6028 is monitored by temperature monitor during the constant-current and constant-voltage charging. There are two LEDs indicate the charge mode.  The HX6028 charger converters are available in the MSOP-8L packages (or upon request).
