The USB power status open drain output (USBPWR) has
two states: pull-down and high impedance. The high imped-
ance state indicates that the LTC4075HVX is being powered
from the USBIN input. The pull-down state indicates that
the charger is either powered from DCIN or is in a UVLO
or an OVLO condition (see Table 1).
Thermal Limiting
An internal thermal feedback loop reduces the programmed
charge current if the die temperature attempts to rise

above a preset value of approximately 125°C. This feature
protects the LTC4075HVX from excessive temperature and
allows the user to push the limits of the power handling
capability of a given circuit board without risk of damag-
ing the device. The charge current can be set according
to typical (not worst-case) ambient temperature with the
assurance that the charger will automatically reduce the
current in worst case conditions. DFN package power
considerations are discussed further in the Applications
Information section.
