HV311LG-G

HV311LG-G Description

The HV311LG-G is a general-purpose hot swap controller designed by Microchip Technology. This device is engineered to manage the safe insertion and removal of circuit boards in live systems, ensuring minimal disruption and maintaining system integrity. The HV311LG-G operates within a wide supply voltage range of 10V to 90V and draws a supply current of only 600 µA, making it highly efficient for a variety of applications.

The controller is housed in a surface-mount package, specifically in a Tape & Reel (TR) format, which is ideal for automated assembly processes. It features a single channel and does not include internal switches, providing flexibility in circuit design. The HV311LG-G is also REACH unaffected and RoHS3 compliant, ensuring it meets the latest environmental and safety standards.

HV311LG-G Features

The HV311LG-G offers several advanced features that enhance its functionality and reliability. Key features include:

• Auto Retry: Automatically attempts to re-establish a connection after a fault, reducing downtime and improving system availability.
• Fault Timeout: Provides a safety mechanism by limiting the duration of fault conditions, protecting the system from prolonged exposure to potentially harmful conditions.
• Latched Fault: Ensures that faults are captured and retained, allowing for detailed diagnostics and troubleshooting.
• Programmable Features: The controller includes programmable circuit breaker, current limit, overvoltage protection (OVP), and undervoltage lockout (UVLO) features. These programmable options allow for customization to meet specific application requirements.

HV311LG-G Applications

The HV311LG-G is well-suited for a wide range of general-purpose applications where hot swapping is necessary. Its robust design and wide operating voltage range make it ideal for use in:

• Telecommunications Equipment: Ensuring that line cards and other modules can be safely inserted and removed without powering down the entire system.
• Data Centers: Facilitating the maintenance and upgrade of servers and storage devices without interrupting service.
• Industrial Control Systems: Allowing for the seamless replacement of faulty components in real-time, minimizing production downtime.
• Medical Equipment: Enabling the safe exchange of critical components in systems that require continuous operation.

Conclusion of HV311LG-G

The HV311LG-G from Microchip Technology is a versatile and reliable hot swap controller that offers significant benefits for applications requiring safe and efficient board insertion and removal. Its wide operating voltage range, low supply current, and programmable features make it a robust solution for various general-purpose applications.
