LT4356HMS-1#PBF

Overview

The LT4356HMS-1#PBF is a high voltage ideal diode controller designed for hot-swap and ORing applications. It operates with an external N-channel MOSFET to provide low on-resistance and fast response times. The device supports input voltages up to 100V and includes programmable current limit, soft-start, and fault protection features. It ensures controlled inrush current during power-up and protects against overcurrent conditions.

Feature Summary

• Integrated high-voltage ideal diode controller for seamless power path management
• Supports external N-channel MOSFET for low conduction loss
• Built-in protection against overcurrent, reverse current, and thermal stress

Applications

• Hot-swap controllers in server and storage systems
• Redundant power supply ORing circuits
• Industrial equipment requiring robust power switching

Procurement Notes

Verify the exact part number suffix matches your design requirements. Confirm package type and temperature range specifications before ordering. Ensure compatibility with external MOSFET selection based on voltage and current ratings. Check manufacturer documentation for latest revisions and application notes.

Selection Notes

Select this component when high-side switching with precise current limiting is required. Consider external MOSFET characteristics such as Rds(on) and gate charge. Evaluate system voltage levels and fault response time needs. Review thermal performance under expected load conditions.
