NOTES:

than the POR threshold, no output pin can be used for indication.

4. For junction temperature from -40°C to120°C.

5. The charge current can be affected by the thermal foldback function if the IC under the test setup cannot dissipate the heat.

6. Guaranteed by characterization or correlation to other test.

Electrical Specifications

Typical Values Are Tested at VIN = 5V and the Ambient Temperature at 25°C. All Maximum and Minimum

Values Are Guaranteed Under the Recommended Operating Supply Voltage Range and Ambient Temperature

Range, Unless Otherwise Noted. (Continued)
