The LM5050MK-1 from Texas Instruments is a high side OR-ing FET controller designed to manage the power distribution in systems that require multiple power sources. This advanced controller is ideal for applications such as servers, telecom, and data centers where redundancy is crucial for uninterrupted power supply and high reliability.

Key Features

• High-Side OR-ing Control: The LM5050MK-1 provides intelligent control of a high-side N-channel FET, ensuring seamless transition between multiple power sources.
• Wide Operating Voltage Range: With an operating range from 4V to 20V, it supports a broad spectrum of applications and power architectures.
• Reverse Current Blocking: The controller prevents reverse current from flowing when the voltage on the output bus is higher than the input, protecting downstream circuits.
• Charge Pump for Enhanced Performance: An integrated charge pump ensures the gate of the external FET is driven high enough to provide a low on-resistance path.
• Fast Turn-Off Under Fault: The LM5050MK-1 can quickly turn off the FET when a fault condition is detected, minimizing the risk of damage to components.

Applications

• Redundant Power Systems
• Telecom and Network Equipment
• Servers and Storage Systems
• Industrial Power Supplies
