Description
The AW32006ZXXX is a highly-integrated Li-Ion/Li-Polymer battery linear charger. The AW32006ZXXX is targeted at space limited portable applications. The chip can take input power from either an AC adaptor or a USB port to charge the battery. The charger accepts an input voltage up to 28V but is disabled when the input voltage exceeds the OVP threshold, typically 6.8V (AW32006L) /13.5V (AW32006H), to prevent excessive power dissipation.
The charge process of AW32006ZXXX includes: Pre-Charge, Constant Current Charging and Constant Voltage Regulation. The charge current is programmable with external resistor. The charge process runs automatically. In all charge phases, an internal control loop monitors the IC junction temperature and reduces the charge current if an internal temperature threshold is exceeded. Additionally, input over voltage protection, input under voltage lockout protection and input headroom voltage detection are integrated for good input source monitor.
