The power supply status output (
PWR)hastwostates:pull-
down and high impedance. The pull-down state indicates
that power is present at either DCIN or USBIN. This output
is strong enough to drive an LED. If no power is applied at
either pin, the
PWR pin is high impedance, indicating that
the LTC4075 lacks sufcient power to charge the battery.
The pull-down state is capable of sinking up to 10mA.
The USB power status output (USBPWR) has two states:
pull-down and high impedance. The high impedance
state indicates that the LTC4075 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
condition (see Table 1). The pull-down state is capable of
sinking up to 1mA.
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 105°C. This feature protects
the LTC4075 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.
