LTC4411ES5#TRMPBF

LTC4411 is a ideal diode IC, capable of supplying upto 2.6A from an input voltage between 2.6V and 5.5V. It contains a 140Mohm 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 upto 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 device is not conducting forward current. It is used in applications such as cellular phones, handheld computers, digital cameras, USB peripherals, uninterrupted supplies, logic controlled power switch.
