NOTE:
3. The 4.2V V
BAT
is selected so that the STATUS output can be used as the indication for the offset comparator output indication. If the V
BAT
is
lower than the POR threshold, no output pin can be used for indication.
4. The charge current can be affected by the thermal foldback function if the IC under the test setup cannot dissipate the heat.
Electrical Specifications
Typical Values Are Tested at V
IN
= 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.
