Linear Technology LTC4211IMS8#PBF Hot Swap Controller

The LTC4211IMS8#PBF is a sophisticated hot swap controller designed by Linear Technology to enable safe board insertion and removal from a live backplane. This component is housed in an MSOP-8 package and is engineered to manage the inrush current during the plug-in event, thus protecting both the connector and the backplane from the stress of electrical arcing and preventing the power supply from collapsing due to the sudden load.

Key Features

• Advanced Electronic Circuit Breaker: The LTC4211IMS8#PBF is equipped with an electronic circuit breaker function that provides precise overcurrent protection by using a sense resistor to monitor the load current.
• Adjustable Overcurrent Protection: Users can set the overcurrent threshold to match specific requirements, ensuring that the system is safeguarded against a wide range of potential fault conditions.
• Automatic Retry or Latch Off: After an overcurrent fault, the device can be configured to either automatically attempt to restart the power or to latch off until the system is reset, offering flexibility in handling fault conditions.
• Under Voltage Lockout (UVLO): The UVLO feature ensures that the controller remains off if the supply voltage is insufficient, preventing malfunctioning during low voltage conditions.
• Gate Voltage Clamped: To protect the external MOSFET from overvoltage, the gate voltage is clamped, which also aids in controlling the inrush current.

Applications

The LTC4211IMS8#PBF hot swap controller is ideal for a variety of applications where electronic boards need to be inserted into live systems without causing disruption or damage. These include:

• RAID Systems
• Server Hot Swap Supplies
• Network Routers and Switches
• Industrial Systems
