描述 Description

The LS2405IDD23 emulates a 5A very low forward voltage diode

that is used in high current diode and diode-OR applications. The

LS2405IDD23 integrates a 35mohm N-Channel MOSFET to obtain

higher efficiency and smaller board area to replace a Schottky

diode. LS2405IDD23 detects the forward voltage drop across the

MOSFET to ensure the current transfer from one path to the other

path smoothly, so it is easily used in the multiple power supplies

OR applications that can effectively increase total system reliability.

When the input supply fails or is shorted to ground, a fast circuitry

can turn off the MOSFET immediately to reduce the reverse

current.

LS2405IDD23 is available in low profile 8 lead DFN 2mmx3mm

package.
