The LTC4411 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 140mΩ P-channel MOSFET connecting IN to OUT. During normal forward operation, the drop across the MOSFET is regulated to as low as 28mV. Quiescent current is less than 40µA for load currents up to 100mA. If the output voltage exceeds the input voltage, the MOSFET is turned off and less than 1µA of reverse current flows from OUT to IN. Maximum forward current is limited to a constant 2.6A (typical) and internal thermal limiting circuits protect the part during fault conditions.

An open-drain STAT pin indicates conduction status. The 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 25µA. When shut off, the LTC4411 indicates this condition with a low voltage on the status signal.
