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.
