Introducing the LT1642CGN from Linear Technology

The LT1642CGN is a highly integrated and versatile electronic component designed by Linear Technology, a brand synonymous with precision, durability, and innovation in the field of analog integrated circuits. This particular product is a hot swap controller that enables safe board insertion and removal from a live backplane.

Key Features and Benefits

• Safe Insertion and Removal: The LT1642CGN allows electronic equipment to be added or removed without the need to power down the entire system. This feature is crucial for systems that require high availability and minimal downtime.
• Adjustable Current Limit: This device provides an adjustable current limit, which helps protect the power source and the electronic components from over-current conditions that could potentially cause damage.
• Overcurrent Fault Timer: The built-in overcurrent fault timer ensures that temporary faults do not lead to system shutdown, while persistent overcurrent conditions trigger a fault response to protect the system.
• Wide Operating Voltage Range: The LT1642CGN operates over a wide voltage range, accommodating various system requirements and ensuring compatibility with diverse applications.
• Gate Drive for External N-Channel MOSFET: The controller includes a gate drive for an external N-channel MOSFET, providing efficient power management and thermal protection.
• Undervoltage Lockout: An undervoltage lockout feature prevents the system from operating at dangerously low voltages, which could otherwise lead to erratic behavior or damage.

Applications

The LT1642CGN is well-suited for a range of applications, including but not limited to:

• RAID Systems
• Redundant Power Supplies
• Hot Swap Rack Systems
• Network Servers and Storage Systems

Its robust design ensures reliable performance in environments where continuous system operation is critical. The LT1642CGN comes in a narrow 16-lead SSOP package, providing a compact solution that is easy to integrate into your existing designs.

Whether you're developing enterprise-level servers, telecommunications equipment, or industrial systems, the LT1642CGN from Linear Technology offers the performance and reliability needed to maintain seamless operation and system integrity during hot swap events.
