LTC4211IMS#PBF - Hot Swap Controller from Linear Technology

The LTC4211IMS#PBF is a sophisticated hot swap controller designed by Linear Technology to enable safe board insertion and removal from a live backplane. It is housed in a compact MSOP-10 package and operates over a wide voltage range, making it an ideal choice for managing the power supply connection in high-availability systems.

Key Features

• Wide Operating Voltage Range: The LTC4211IMS#PBF can handle a voltage range from 2.5V to 16.5V, catering to a broad spectrum of applications and ensuring compatibility with various system voltages.
• Adjustable Current Limit: This hot swap controller allows for precise setting of the current limit threshold via an external resistor. This flexibility ensures protection tailored to the specific needs of the connected circuitry.
• Overcurrent Protection: In the event of overcurrent conditions, the device responds quickly to protect both the motherboard and the card being inserted, helping to prevent damage to electronic components.
• Automatic Retry or Latch Off: After a fault condition, the LTC4211IMS#PBF can be configured to either attempt a power-on again (auto-retry) or to latch off, depending on the needs of the application.
• Under Voltage Lockout (UVLO): The controller ensures that the power is only enabled when the supply voltage is above a certain threshold, preventing malfunction due to insufficient voltage.
• Gate Voltage Clamping: To protect the external N-channel MOSFET, the LTC4211IMS#PBF clamps the gate voltage, preventing it from exceeding the safe operating limits.

Applications

The LTC4211IMS#PBF is versatile and can be utilized in various applications that require hot swapping capabilities, such as:

• Server and Network Equipment
• RAID Systems
• Industrial Computers
• Telecommunications Infrastructure
