LTC4358CFE#PBF

LTC4358 is a 5A ideal diode that uses an internal 20Mohm N-channel MOSFET to replace a schottky diode when used in diode-OR and high current diode applications. It reduces power consumption, heat dissipation, and PC board area. It easily ORs power supplies together to increase total system reliability. In diode-OR applications, this device 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. It is widely used in applications such as N+1 redundant power supplies, high availability systems, telecom infrastructure, automotive systems etc.

• Operating voltage range is 9V to 26.5V
