NOTES:

1. The 4.5V V_BATis selected so that the

output can be used as the indication for the offset comparator output indication. If

PPR

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

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