LINE CHARACTERISTICS
Unless otherwise specified, the test conditions are as specified in
Typical values are characteristic of the device and are the result of engineering evaluations. Typical values are for information
purposes only and are not a part of the testing requirements. Minimum and maximum values apply across the operating
temperature range and the entire battery range unless otherwise specified. Typical is defined as T
