The power supply status output (PWR) has two states:
pull-down and high impedance. The pull-down state
indicates that power is present at either DCIN or USBIN.
If no power is applied at either pin, the PWR pin is high
impedance, indicating that the LTC4076 lacks sufficient
powertochargethebattery.Thepull-downstateiscapable
of sinking up to 10mA.
Thermal Limiting
Aninternalthermalfeedbackloopreducestheprogrammed
chargecurrentifthedietemperatureattemptstoriseabove
apresetvalueofapproximately105°C.Thisfeatureprotects
the LTC4076 from excessive temperature and allows the
user to push the limits of the power handling capability of
a given circuit board without risk of damaging 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 power considerations are discussed
further in the Applications Information section.
