LTC1647-3CGN#PBF - Dual Hot Swap Controller

The LTC1647-3CGN#PBF is a sophisticated dual hot swap controller from Linear Technology, designed to manage the safe insertion and removal of printed circuit boards from a live backplane. This component is housed in a 16-lead SSOP package and is engineered to provide a reliable solution for systems that require hot-swapping capabilities to minimize downtime and maintain continuous operation.

Key Features

• Independent Control: This controller offers two independent channels, allowing for the management of two separate power supplies or two distinct sections of a system.
• Adjustable Current Limit: The LTC1647-3CGN#PBF provides an adjustable overcurrent limit threshold via an external resistor, which ensures protection against excessive current draw that could damage circuit components.
• Programmable Timer: An onboard timer can be programmed to set the duration of the overcurrent condition before a fault is declared, providing additional flexibility for system designers.
• High Voltage Operation: The device is capable of operating with supply voltages up to 16.5V, accommodating a wide range of applications and system requirements.
• Glitch Filter: An integrated glitch filter prevents false triggering due to transients, ensuring stable operation during the insertion or removal of boards.

Advanced Protection Features

• Under-Voltage Lockout: The LTC1647-3CGN#PBF includes under-voltage lockout (UVLO) protection, which ensures that the hot swap operation does not commence until the supply voltage reaches a safe level.
• Overcurrent Protection: In the event of an overcurrent condition, the device will act to disconnect the load, safeguarding the electronic components from potential damage.
• Thermal Shutdown: To prevent overheating, the controller is equipped with a thermal shutdown feature that automatically disables the output if the internal temperature exceeds safe operating limits.

With its robust feature set, the LTC1647-3CGN#PBF is an ideal choice for server farms, telecom systems, and industrial applications where uninterrupted service is critical. Its ability to manage power distribution safely and effectively makes it a cornerstone component in high-availability systems.

Overall, the LTC1647-3CGN#PBF from Linear Technology represents a reliable, high-performance solution for hot swap control, ensuring system integrity and protecting valuable electronic equipment during maintenance or upgrades.
