The LM5050Q1MKX-1/NOPB is a high-performance, high-voltage ORing FET controller designed by Texas Instruments to enhance power supply reliability. This device is particularly suitable for automotive, telecommunications, and industrial applications where redundant power supply systems are essential for continuous operation and system integrity.

Key Features

• Voltage Range: It operates over a wide voltage range, accommodating systems that require voltage ORing from 5.5V up to 75V, making it versatile for various applications.
• Gate Drive: The integrated charge pump ensures a proper gate drive for external N-Channel MOSFETs, which allows for efficient control of the pass-through voltage.
• Reverse Current Blocking: The LM5050Q1MKX-1/NOPB provides reverse current blocking capability, which prevents current from flowing backward through the FET when the voltage on the load side is higher than the source side.
• High-Side ORing: This device is designed for high-side ORing, which means it can be placed closer to the supply, minimizing voltage drops and power dissipation.
• Automotive-Qualified: The 'Q1' designation indicates that the device is qualified for automotive applications, meeting the stringent requirements of the automotive industry for reliability and performance.
• Thermal Shutdown: It features a thermal shutdown mechanism that protects the device under over-temperature conditions.

Applications

• Redundant Power Supply Systems
• Automotive Power Systems
• Telecom and Datacom Power Systems
• Industrial Power Distribution Networks

Product Compliance

The 'NOPB' suffix indicates that the product is lead-free and RoHS compliant, which means it is manufactured without the use of hazardous substances such as lead, making it environmentally friendly and suitable for use in a wide range of international markets.
