LTC4355IDE#PBF

OR Controllers, Ideal Diodes Overview

The LTC4355IDE#PBF is a positive high voltage ideal diode-OR controller manufactured by Analog Devices Inc. It operates within an input voltage range of 9 V to 80 V and supports a maximum output voltage of 80 V. The device functions in the industrial temperature range, operating from -40°C to +85°C. It is housed in a 16-lead SOIC package with an exposed pad for thermal management.

OR Controllers, Ideal Diodes Feature Summary

• Integrates input supply monitoring and fuse monitoring capabilities alongside ideal diode-OR functionality.
• Provides precise current sharing for parallel power supply configurations without requiring external components.

OR Controllers, Ideal Diodes Applications

• High voltage redundant power systems
• Input ORing for bus distribution
• Parallel power supply current sharing

OR Controllers, Ideal Diodes Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature grade. Confirm availability status as supply may be limited or subject to factory order constraints. Ensure compatibility with existing board layouts regarding the SOIC-16 footprint.

OR Controllers, Ideal Diodes Selection Notes

Select this component for applications requiring robust high-voltage ideal diode control with integrated system health monitoring. The SOIC-16 package offers a balance of thermal performance and pin count suitable for dense PCB designs. Verify that the 9V to 80V operating range aligns with the target system voltage rails.

OR Controllers, Ideal Diodes Part Context

This part belongs to the LTC4355 series of ideal diode controllers. It is distinct from other variants such as the MSOP-16 packaged LTC4355HMS#TRPBF due to its specific package form factor and industrial temperature rating. The series focuses on high-voltage power management solutions.

OR Controllers, Ideal Diodes Replacement Considerations

LTC4355IS#PBF serves as a direct alternative within the same family, differing primarily in package style (SOIC-16 vs SOIC-16) and potentially temperature grade verification. Cross-reference datasheets for exact pinout and electrical parameter alignment before substitution.
