LM73100 23V 5A Ideal Diode Power Protection Module

The LM73100 Ideal Diode Power Protection Module is a high-efficiency solution for controlling current flow in DC power systems. Designed to replace traditional diodes, this module allows current to flow in one direction while minimizing voltage drop and power loss. Instead of the large forward voltage drop found in standard diodes, the LM73100 uses internal back to back MOSFETs to achieve very low on resistance, improving efficiency in high current applications.

This module is suitable for systems operating from 3V to 23V DC and supports load currents up to 5A. It is ideal for power path management in battery powered systems, solar inputs, and other applications where efficiency and protection are critical.
