The LTC ? 4411 is an ideal diode IC, capable of supplying up
to 2.6A from an input voltage between 2.6V and 5.5V. The
LTC4411 is housed in a 5-lead 1mm profile SOT-23
package.
The LTC4411 contains a 140m ? P-channel MOSFET con-
necting IN to OUT. During normal forward operation, the
drop across the MOSFET is regulated to as low as 28mV.
Quiescent current is less than 40 μ A for load currents up to
100mA. If the output voltage exceeds the input voltage, the
MOSFET is turned off and less than 1 μ A of reverse current
flows from OUT to IN. Maximum forward current is limited
to a constant 2.6A (typical) and internal thermal limiting cir-
cuits protect the part during fault conditions.
An open-drain STAT pin indicates conduction status. The
APPLICATIO S
STAT pin can be used to drive an auxiliary P-channel
MOSFET power switch connecting an alternate power

source when the LTC4411 is not conducting forward
current.
An active-high control pin turns off the LTC4411 and
reduces current consumption to less than 25 μ A. When
shut off, the LTC4411 indicates this condition with a low
voltage on the status signal.
