LTC4217IFE#PBF - Hot Swap Controller from Linear Technology

The LTC4217IFE#PBF is a sophisticated hot swap controller designed by Linear Technology to ensure safe insertion and removal of electronic boards from live backplanes and other power sources. This component provides a controlled ramp-up of the board supply voltage to prevent glitches on the power bus, protect the connectors, and avoid any damage to sensitive components due to inrush currents.

Key Features

• Wide Operating Range: The device operates with supply voltages from 2.9V to 26.5V, making it suitable for a broad range of applications.
• Adjustable Current Limit: Users can set the overcurrent threshold according to their specific needs, ensuring protection against excessive current draw.
• Fast Overcurrent Protection: The LTC4217IFE#PBF reacts quickly to overcurrent conditions, providing rapid response to protect the circuit.
• Circuit Breaker Function: An integrated circuit breaker function helps to prevent catastrophic failures by disconnecting the load in case of persistent overcurrent conditions.
• Power Good Output: A "power good" status output is available to indicate when the output voltage is within the regulated range, which is useful for sequencing and system monitoring.
• High Availability: The device features an automatic retry after a fault, enhancing system reliability and uptime.
• Thermal Shutdown: To protect against overheating, the LTC4217IFE#PBF includes a thermal shutdown mechanism that turns off the device if it exceeds a certain temperature threshold.
