The LTC4211IMS#TRPBF is a sophisticated hot swap controller from Linear Technology, designed to enable safe board insertion and removal from a live backplane. This product is ideal for protecting systems where the need to change boards without powering down is essential, such as in servers, telecommunications, and network equipment.

Key Features

• Integrated MOSFET Control: The LTC4211IMS#TRPBF controls the gate voltage of an external N-channel MOSFET to allow a board to be safely inserted and removed from a live backplane.
• Adjustable Current Limit: This device features an adjustable overcurrent limit, which protects the system and the card from damage due to excessive current.
• Fast Overcurrent Protection: The fast overcurrent circuitry responds to faults such as short circuits in less than 1μs, ensuring rapid protection.
• Automatic Retry or Latch Off: Upon detecting an overcurrent condition, the LTC4211IMS#TRPBF can be programmed to either automatically retry power-up or latch off until the system is reset.
• Under-voltage and Over-voltage Lockout: The under-voltage and over-voltage lockout ensures that the board is only powered when the supply voltage is within a valid range.
• Multi-function Timer: A multi-function timer offers flexibility in controlling the circuit breaker's response time, the power-up rate, and the detection time for overcurrent events.
• Thermal Shutdown: Additional protection is provided by a thermal shutdown mechanism that prevents overheating of the controller.
