Download Technical Datasheet

The LTC®4357 is a positive high voltage ideal diode controller that drives an external N-channel MOSFET to replace a Schottky diode. When used in diode OR and high current diode applications, the LTC4357 reduces power consumption, heat dissipation, voltage loss and PC board area. The LTC4357 easily ORs power sources to increase total system reliability.

In diode-OR applications, the LTC4357 controls the forward voltage drop across the MOSFET to ensure smooth current transfer from one path to the other without oscillation. If the power source fails or is shorted, a fast turn-off minimizes reverse current transients.
