The LTC1422I is a sophisticated hot swap controller designed by Linear Technology, engineered to enable safe insertion and removal of printed circuit boards from a live backplane. This integrated circuit (IC) is particularly suitable for high-availability systems where continuous operation is critical, and maintenance or upgrades need to be performed without system shutdown.

Key Features

• Safe Board Insertion and Removal: The LTC1422I ensures that electronic boards can be inserted into a live backplane without causing glitches or short circuits that could disrupt system operation.
• Adjustable Current Limit: It provides an adjustable current limit feature, which can be set via an external resistor. This allows for precise control over the maximum amount of current supplied to the board during insertion.
• Overcurrent Protection: The device includes a fast-acting overcurrent protection mechanism that helps protect both the backplane and the board from damage due to excessive current draw.
• High Voltage Operation: The LTC1422I is capable of operating at high voltages, making it suitable for systems that require higher power levels.
• Temperature Range: The 'I' version of the LTC1422 indicates that it is designed for industrial applications, with an operating temperature range that typically spans from -40°C to +85°C.
