Note 4:
When V

IN
, the P-channel FET will be on
in parallel with the bypass PFET reducing the overall R
DS(ON)
.
Note 5:
This IC includes overtemperature protection that is intended to
protect the device during momentary overload conditions. Junction
temperature will exceed 125
°
C when overtemperature protection is active.
Continuous operation above the specified maximum operating junction
temperature may impair device reliability.
