LTC4242CG#PBF - Hot Swap Controller from Linear Technology
The LTC4242CG#PBF is a sophisticated, integrated circuit designed for managing the hot insertion and removal of cards in high-availability electronic systems. Manufactured by Linear Technology, now part of Analog Devices, this hot swap controller enables safe board insertion and removal from a live backplane without causing glitches or disruptions in the system's power supply or data buses.
Key Features:
- Dual Slot Hot Swap Controller: It is built to handle two slots simultaneously, making it ideal for dense and complex systems where space and efficiency are at a premium.
- Wide Operating Voltage Range: The LTC4242CG#PBF operates with supply voltages ranging from 2.9V to 15V, accommodating a variety of system voltages and ensuring compatibility with different backplane designs.
- Adjustable Overcurrent Protection: It includes adjustable overcurrent protection, which safeguards the system and the card from damage due to excessive current draw.
- Power Good Outputs: The controller provides "power good" outputs for each slot, which can be used to enable a downstream converter or to notify the system that the card is up and running properly.
- Glitch Filtering: The LTC4242CG#PBF offers glitch filtering on the gate drive to prevent false triggering of the external N-channel MOSFET during insertion or removal of the card.
- Compact Design: Housed in a 36-pin SSOP package, this controller is designed for space-constrained applications.
Applications:
The LTC4242CG#PBF is versatile and can be used in a wide array of applications, including:
- RAID Systems
- Servers and Storage Systems
- Network Routers and Switches
- Industrial Computers
- Telecommunications Equipment
With its robust feature set, the LTC4242CG#PBF provides an efficient solution for power management during hot swapping, ensuring minimal downtime and maximum system availability.
