Key Features
- Positive high-voltage ideal diode-OR controller drives external N-channel MOSFET for near-zero forward drop power-ORing
- eFuse-type protection function guards downstream circuitry against overvoltage and reverse current events
- Single-channel design in a compact 16-pin SSOP package simplifies layout in redundant power supply architectures
Applications
The LTC4355HMS#PBF is designed for high-availability servers, telecom equipment, and industrial power systems that require seamless ORing between redundant power inputs. By replacing conventional Schottky diodes with an ideal diode function, it eliminates the power loss and heat associated with diode forward voltage drops in high-current rails. The device also provides eFuse-style protection, making it suitable for backplane power distribution and mission-critical embedded computing platforms.

Frequently Asked Questions
How does the LTC4355HMS#PBF improve efficiency over a traditional Schottky diode in a power-ORing circuit?
By driving an external N-channel MOSFET as an ideal diode, the LTC4355HMS#PBF achieves a near-zero forward voltage drop compared to the 0.3 V to 0.5 V drop of a Schottky diode, significantly reducing conduction losses and heat dissipation in high-current redundant power supply rails used in servers and telecom systems.
What protection feature does the LTC4355HMS#PBF provide beyond simple power-ORing?
In addition to ideal diode-OR functionality, the LTC4355HMS#PBF incorporates an eFuse-type protection feature that detects overvoltage and reverse current conditions on 1 channel, quickly turning off the external MOSFET to protect sensitive downstream loads from damage in backplane and redundant supply designs.
For a redundant 48 V telecom power system, what package and channel count does the LTC4355HMS#PBF offer?
The LTC4355HMS#PBF is a single-channel controller housed in a 16-pin SSOP package, making it straightforward to deploy one device per power input rail in a dual-input 48 V telecom redundancy architecture, minimizing PCB area while maintaining full ideal diode and protection functionality.
