NOTES:

6. The 4.2V VBAT is selected so that the STATUS output can be used as the indication for the offset comparator output indication. If the VBAT is lower than

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

7. 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 VIN = 5V and the ambient temperature at +25°C, unless otherwise noted.
