The HC8032 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 HC8032 ideally suited for portable applications. The charge current can be programmed externally with a single resistor, which may be programmed up to 0.9A. HC8032 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 HC8032 is monitored by temperature monitor during the constant-current and constant-voltage charging. There are two LEDs indicate the charge mode.
