About the Product
LTC4357HMS8 Ideal Diode Controller – 9V-80V, 500μA | MOSFET Replacement for Power Systems
The LTC4357HMS8 is a high-performance ideal diode controller designed to work with an external N-channel MOSFET to create efficient diode OR-ing or reverse protection solutions. Operating across a wide input voltage range of 9V to 80V and consuming only 500μA of quiescent current, this controller provides fast response to prevent reverse conduction while maintaining low forward voltage drop, ensuring maximum system efficiency.

Superior Protection for Power Supply Systems
Engineered for demanding applications, the LTC4357HMS8 offers robust protection against reverse currents and supports smooth switchover between redundant power sources. Its ability to drive an external MOSFET makes it a superior replacement for traditional Schottky diodes, offering reduced power dissipation and heat generation. This makes it ideal for use in power distribution systems, telecom equipment, cryptominer power boards, and industrial electronics where efficiency and reliability are critical.
