Linear Technology LTC4413EED Dual Diode ORing PowerPath Controller

The LTC4413EED from Linear Technology is a sophisticated integrated circuit designed to enhance power supply reliability through its Dual Diode ORing PowerPath Controller functionality. This device allows for seamless transition between two power sources, ensuring that the load remains powered even if one source fails or is disconnected.

Key Features:

• Low Voltage Drop: The LTC4413EED has an exceptionally low voltage drop, thanks to its internal MOSFETs, which are far more efficient than traditional Schottky diodes. This results in reduced heat dissipation and improved power efficiency, making it ideal for battery-powered applications.
• Automatic Switching: The device automatically switches between two power sources without intervention, providing uninterrupted power to the load. It can handle input voltages from 2.5V to 5.5V, accommodating a wide range of power supplies.
• Reverse Battery Protection: Built-in reverse battery protection safeguards the device and downstream circuits from potential damage that can occur if a battery is inserted backward.
• Status Flag Output: The LTC4413EED includes a status flag output that indicates which power source is currently being used. This feature allows for system monitoring and can be used to trigger alarms or other system responses.
• Compact Package: Available in a compact 10-lead DFN package, the LTC4413EED saves valuable board space and is suitable for space-constrained applications.

Applications:

The LTC4413EED is versatile and can be used in a variety of applications where dual power sources are needed or desired for redundancy. Some common applications include:

• Portable Electronic Devices
• Automotive and Industrial Systems
• Medical Equipment
• Redundant Power Supply Systems

The LTC4413EED's advanced features and reliable performance make it a top choice for engineers and designers looking to enhance the power supply reliability of their systems. Its ability to manage power between two sources seamlessly, coupled with its protective features and compact size, makes it an invaluable component in any critical power management design.
