USB Port Multimedia Switch Featuring Automatic Select and Accessory Detection

Fairchild Semiconductor 

9. Electrical Specifications

9.1. Absolute Maximum Ratings

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable

above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition,

extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute

maximum ratings are stress ratings only.

9.2. Recommended Operating Conditions

The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended operating

conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not recommend

exceeding them or designing to Absolute Maximum Ratings.

Note:

14. Fairchild does not guarantee operation below 3.0V.

15. Between 5.5 to OVP starting voltage, the charger FET is still closed so that charger IC can charge battery even with

5.9~6.0V travel adaptor.
