8602GN

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
