The AW32001A is a highly-integrated Li-Ion/Li-Polymer battery linear charger with system power path management. The charge process of AW32001A includes: Pre-Charge, Fast Charge and Constant Voltage Regulation. The charge parameters and operating modes are programmable through I2C interface. The charge process runs automatically and recharging occurs when the battery voltage drops below VBAT_REG-VRECH after the charge done status.
