The LTC4417IUF#PBF from Linear Technology is a cutting-edge power management IC designed to control three separate power sources, ensuring that the highest priority supply is delivered to the load. This triple supply prioritized PowerPath controller is ideal for systems that require a reliable and seamless transition between multiple power supplies such as battery backup systems, redundant power supply systems, and multi-source power systems.

Key Features:

• Three Inputs, One Output: Manages power from three sources with automatic switching to the highest priority source available.
• Wide Operating Voltage Range: Compatible with a broad range of supply voltages from 2.5V to 5.5V, allowing for flexible usage across various applications.
• Low Loss PowerPath Selection: Features low on-resistance (R<sub>ON) internal switches to minimize power loss during operation.
• Adjustable Priorities: Prioritization is configurable through external resistors, providing the flexibility to adapt to different system requirements.
• Reverse Blocking: Prevents reverse current flow from the output to the inputs, safeguarding the power sources.
• Compact Package: Housed in a compact 20-lead QFN package (3mm x 3mm), saving valuable board space.
