Product Overview: LM5067MW-1/NOPB

The LM5067MW-1/NOPB is a high-performance Negative Hot Swap / Power Management Integrated Circuit (IC) designed by Texas Instruments. This state-of-the-art device offers intelligent control of the power supply connection and disconnection for electronic equipment in negative voltage environments. It is specifically engineered to handle systems with supply voltages ranging from -9V to -80V, making it a versatile solution for a wide array of applications in industrial, telecom, and datacom sectors.

Key Features

• Voltage Range: The LM5067MW-1/NOPB operates efficiently across a broad voltage range, accommodating systems from -9V to -80V, which is ideal for negative supply rail applications.
• Current Monitoring: With an integrated current monitoring feature, the device allows for real-time observation of the load current, aiding in system diagnostics and protection.
• Programmable UVLO: The under-voltage lockout (UVLO) is programmable, ensuring that the system operates only when the supply voltage is within an acceptable range, thereby protecting the load and increasing system reliability.
• Overcurrent Protection: It features robust overcurrent protection which prevents damage to the system components by limiting the output current during fault conditions.
• Thermal Shutdown: The thermal shutdown mechanism enhances the safety of the system by turning off the power switch if the temperature exceeds a predetermined threshold.
• Power Good Output: A 'Power Good' output signal is provided, which can be used to enable downstream converters after a successful power-up sequence.

Applications

The LM5067MW-1/NOPB is suitable for a variety of applications, particularly where negative voltage power rails are prevalent. It is commonly used in:

• Telecom and Datacom Infrastructure
• Industrial Equipment
• Network Routers and Switches
• Negative Voltage Power Modules
• Redundant Power Systems

Package and Quality

The device is available in a compact 16-pin VSSOP (MSOP) package, which allows for space-efficient designs. The NOPB designation indicates that the product is lead-free and RoHS compliant, meeting environmental standards and reducing hazardous waste. This reflects Texas Instruments' commitment to environmental sustainability while delivering high-quality and reliable components for advanced electronic systems.
