Linear Technology LTC4419IMSE#PBF PowerPath Controller

The LTC4419IMSE#PBF is a sophisticated PowerPath controller designed by Linear Technology, now part of Analog Devices, that ensures seamless transitions between multiple power sources in a system. This integrated circuit is engineered to manage power between two supplies, prioritizing the input with the highest voltage within a specified range. It is particularly useful in systems that require a reliable and uninterrupted power supply, such as portable devices, automotive applications, and industrial systems.

Key Features:

• Automatic Switching: The LTC4419IMSE#PBF automatically switches to the higher priority supply when two valid power sources are present, providing a seamless transition and minimizing the risk of power interruption.
• Low Voltage Drop: With its low on-resistance (R_ON) of just 50mΩ, the device ensures minimal voltage drop across the internal MOSFETs, preserving energy and maintaining efficiency.
• Wide Operating Range: The device operates with an input voltage range from 2.5V to 5.5V, accommodating a variety of power sources and applications.
• Adjustable Prioritization: Users can configure the priority of the input sources through an external resistor divider, offering flexibility in different system designs.
• Reverse Input Protection: The LTC4419IMSE#PBF is equipped with built-in reverse input protection, safeguarding the system against potential damage from incorrectly installed batteries or power supplies.
• Compact Package: Housed in a 12-Lead MSOP package, the product is designed for space-constrained applications, providing a compact power management solution.

Applications:

• Redundant Power Supplies
• Automotive Power Systems
• Portable and Battery-Powered Equipment
• Industrial Power Management
• Uninterruptible Power Supplies (UPS)

The LTC4419IMSE#PBF is a testament to Linear Technology's commitment to reliability and innovation in power management solutions. Its robust feature set and flexible design make it an ideal choice for managing dual supply systems that cannot afford to lose power, ensuring devices operate smoothly and efficiently under varying power conditions.
