Description
8602GN is a highly integrated battery charge controller with adapter current sense and an internal wakeup circuit. It can operate as a stand-alone charger or under the supervision of a host microcontroller.
Features
• Supports fast-charge current
• Dynamic AC adapter current allocation for maximum charge rate
• High efficiency of >94%
• Provides 0.7% constant voltage operation accuracy
• Charges various battery chemistries, including Lilon with 2 to 4 cells, NiCd, and NiMH
• Analog inputs to program charging current and charging voltage
• Switches automatically to power-saving mode when the AC adapter is not available
• Powerful driver for PMOS switch
• Built-in under-voltage, over-voltage, and short-circuit protection
• 100% maximum switching duty cycle, requiring very low adapter voltage overhead
• Automatic AC Adapter voltage detection
• Easy interface with a microcontroller
• Automatically switches to wake-up current when charging over-discharged batteries or a short circuit is present
• Internal wake-up current function
• Outputs adapter current information
Pinouts
Applications
• Notebook and Portable Electronic Battery Chargers
