LTC4413EDD#PBF

OR Controllers, Ideal Diodes Overview

The LTC4413EDD#PBF is a dual ideal diode controller from Analog Devices, housed in a 10-lead 3mm x 3mm DFN package. It integrates two independent monolithic ideal diodes capable of handling input voltages from 2.5V to 5.5V and delivering up to 2.6A output current per channel. The device utilizes internal P-channel MOSFETs with a maximum on-resistance of 140mΩ at 3.6V, regulating forward voltage drops to approximately 18mV. Static current consumption remains below 80μA at 1A load, while reverse leakage is limited to under 1μA when the output exceeds the input.

OR Controllers, Ideal Diodes FAQ

How does the device handle reverse current flow?

If the output voltage exceeds the input voltage, the internal MOSFET turns off, limiting reverse current to less than 1μA flowing from OUT to IN.

What protection mechanisms are included?

The device features internal constant current limiting set to 2.6A and thermal shutdown circuitry to protect against fault conditions.
