The LT1641-1IS8#TRPBF is a high-performance, positive high voltage hot swap controller from Linear Technology, designed to enable safe insertion and removal of electronic boards from a live backplane. This component is housed in an 8-lead SOIC package and is available in tape and reel packaging, denoted by the suffix 'TRPBF', which stands for tape and reel with lead (Pb)-free finish.

Key Features

• Wide Operating Range: The device operates smoothly over a wide range of input voltages, from 10.8V to 80V, making it versatile for various applications requiring different power levels.
• Adjustable Overcurrent Protection: The LT1641-1IS8#TRPBF provides adjustable overcurrent protection through an external resistor. This feature allows for precise control over the current limit, ensuring protection against excessive currents that can damage the system.
• Gate Drive for External N-Channel MOSFET: The controller features a gate drive for an external N-channel MOSFET, which enables efficient power control and helps to minimize power dissipation.
• Automatic Retry or Latch Off: On detecting a fault condition, the device offers a choice between automatic retry after a fault clears or latch-off for improved system reliability.
• Under Voltage Lockout (UVLO): The built-in UVLO function ensures that the device operates only when the input voltage is within the acceptable range, protecting the system from low voltage conditions.

Applications

The LT1641-1IS8#TRPBF is ideal for a variety of applications, including:

• Hot swap systems
• Power distribution controls
• Server and telecom operations
• Industrial systems
• Network switches and routers
