The LTC4216CDE#PBF is a sophisticated hot swap controller designed by Linear Technology to ensure safe board insertion and removal from live backplanes. This integrated circuit allows a board to be safely hot-plugged by limiting the inrush current to prevent damage to connectors, backplane traces, and power supply components. It is a vital component for systems where maintenance or upgrades need to be performed without disrupting the operation of the rest of the equipment.

Key Features

• Integrated MOSFET: The LTC4216CDE#PBF comes with an onboard N-channel MOSFET that can control the power supply to the load with precision.
• Adjustable Current Limit: This device provides an adjustable overcurrent limit function which protects the system from excessive current draw that could lead to damage.
• Overtemperature Protection: It features an overtemperature shutdown mechanism that ensures the protection of the board and the power system in the event of excessive heat.
• Undervoltage Lockout: The LTC4216CDE#PBF is equipped with an undervoltage lockout (UVLO) feature that prevents operation at dangerously low voltages, which could otherwise lead to erratic system behavior.
• Compact Design: Housed in a 12-lead DFN package, this hot swap controller is designed for space-constrained applications while providing robust protection features.
