LTC4354IDDB#TRMPBF

The LTC4354IDDB#TRMPBF is a negative voltage diode-OR controller from Analog Devices, designed to drive two external N-channel MOSFETs. This component replaces traditional Schottky diodes and heat sinks, significantly reducing power dissipation and saving board space. It is suitable for applications requiring increased system power and reliability through ORing power sources.

Key electrical specifications include a -48V voltage rating and a current rating of 1.2 mA. The device operates within a temperature range of -40°C to 85°C. It features a fast turn-off time of 700 ns, which limits peak fault current and protects pass transistors. The controller is designed for smooth switchover between power sources without oscillation and prevents reverse DC current.

This OR controller is available in an 8-DFN (3x2) package with surface mount mounting type. Its applications include -48V distributed power systems and AdvancedTCA® systems, making it a robust solution for critical power management needs in telecommunications and computing infrastructure.

The LTC4354IDDB#TRMPBF is classified as an OR Controller, Ideal Diodes, within the Power Management IC category. It is manufactured by Analog Devices and comes in an 8-WFDFN exposed pad package.
