Selection Guidelines

Choose this IC when designing small, battery-powered products that need reliable lithium battery charging

Verify that your power adaptor output is within the 4.5V to 6V range

Ensure your battery's charge current requirement does not exceed 500mA

Preferred for applications demanding compactness due to its SOT-23-5 footprint

Check temperature requirements are within -40°C to +85°C

Usage Considerations

Confirm correct IC orientation and pin connection during PCB assembly

Do not exceed recommended input voltage or maximum charge current

Adequate thermal dissipation must be considered during PCB design

Regularly monitor the charging process especially in first implementations

Observe ROHS handling and ESD precautions to avoid device damage
