LTC4357HMS8 Ideal Diode Controller – 9V-80V, 500μA | MOSFET Replacement for Power Systems

High-Voltage Diode OR Controller for Automotive, Telecom & Redundant Power Supplies

Upgrade your power management with the LTC4357HMS8, a high-voltage ideal diode controller that replaces inefficient Schottky diodes in OR-ing, automotive, and telecom systems. This 8-MSOP IC slashes power loss, heat, and PCB space while delivering 80V surge protection and 0.5μs fault response—critical for mission-critical applications.

Ultra-Fast 0.5μs Shutdown | Reverse Current Protection & Low 500μA Operation

Why Engineers Choose LTC4357HMS8:
✔ 80V Wide Input Range – Perfect for 24V/48V automotive load-dump and industrial power redundancy.
✔ Near-Zero Voltage Drop – Uses external N-MOSFETs to minimize losses vs. traditional diodes.
✔ Anti-Oscillation Control – Ensures smooth current switching in dual-power OR-ing circuits.
✔ Reverse Current Blocking – 0.5μs shutdown prevents backflow during short circuits/outages.

Ideal for server farms, base stations, and EV systems, this ADI-sourced IC combines ultra-low 500μA quiescent current with robust MSOP-8 packaging for compact, reliable designs.
