The LTC4211IMS8#TRPBF is a state-of-the-art hot swap controller designed by Linear Technology to provide safe board insertion and removal from live backplanes. This integrated circuit allows a board to be safely connected and disconnected from a live power supply rail without causing disruptive glitches or short circuits, which can damage both the card and the backplane.

Key Features

• Adjustable Overcurrent Protection: The device offers an adjustable overcurrent threshold via an external resistor, ensuring tailored protection for various applications.
• Fast Response Time: It features a fast response to overcurrent conditions, protecting the circuit by quickly turning off the external N-channel MOSFET.
• High Voltage Capability: The LTC4211IMS8#TRPBF can operate with supply voltages up to 6V to 80V, making it versatile for a wide range of hot swap applications.
• Soft-Start Capability: The soft-start function limits inrush current during startup, providing a smooth ramp-up of the card voltage to prevent system voltage sag and reduce stress on the MOSFET.
• Automatic Retry or Latch Off: After a fault condition, the device can be configured to automatically retry power-up or latch off, based on the requirements of the application.
• Compact Package: Supplied in an MSOP-8 package, the LTC4211IMS8#TRPBF is designed for space-constrained applications.
