LTC4413EDD-1#TRPBF

OR Controllers, Ideal Diodes Overview

The LTC4413EDD-1#TRPBF is a dual ideal diode controller from Analog Devices, housed in a 10-pin 3mm x 3mm DFN package. It integrates two independent P-channel MOSFETs to provide low-loss power path switching for input voltages ranging from 2.5V to 5.5V. Each channel supports a maximum forward current of 2.6A with an internal constant current limit and thermal protection circuitry. The device regulates the forward voltage drop to approximately 18mV during normal operation, ensuring high efficiency. Static current consumption remains below 80μA when conducting up to 1A. Reverse leakage is minimized to under 1μA when the output exceeds the input.
