DESCRIPTION

5A Ideal Diode

The LTC®4358 is a 5A ideal diode that uses an internal

20mΩ N-channel MOSFET to replace a Schottky diode

when used in diode-OR and high current diode applica-

tions. The LTC4358 reduces power consumption, heat

dissipation, and PC board area.

The LTC4358 easily ORs power supplies together to in-

crease total system reliability. In diode-OR applications,

the LTC4358 regulates the forward voltage drop across

the internal MOSFET to ensure smooth current transfer

from one path to the other without oscillation. If the power

source fails or is shorted, a fast turnoff minimizes reverse

current transients.
