Product Overview: LTC1421CG#TRPBF

The LTC1421CG#TRPBF is a high-performance Hot Swap Controller designed by Linear Technology to enable safe board insertion and removal from a live backplane. This integrated circuit is an essential component for systems where maintenance and upgrade require the exchange of boards without powering down the entire system. With its robust feature set, the LTC1421CG#TRPBF ensures protection against overcurrent, overvoltage, and short-circuit conditions, thereby enhancing system reliability and uptime.

Key Features

• Electronic Circuit Breaker: The LTC1421CG#TRPBF provides precise control over the inrush current at the time of board insertion, preventing damage to connectors, backplanes, and power supply circuits.
• Adjustable Overcurrent Protection: Users can tailor the overcurrent threshold to match specific application requirements, ensuring optimal protection for various loads.
• Under Voltage Lockout (UVLO): This feature ensures that the controller remains off until the supply voltage reaches a safe operating level, thereby preventing malfunction during low voltage conditions.
• Overvoltage Protection: The device safeguards against voltage spikes that could potentially harm the system components.
• Thermal Shutdown: In the event of excessive heat, the LTC1421CG#TRPBF will shut down to protect itself and the system it controls.
• Gate Voltage Clamping: This protects the external N-channel MOSFET from overvoltage, ensuring a longer lifespan for the switch.
• Status Indicators: Fault and Power Good outputs provide real-time status, which can be used for downstream logic or for diagnostic purposes.

Applications

The LTC1421CG#TRPBF is ideal for a variety of applications including server farms, RAID systems, telecom equipment, and industrial systems where hot-swapping capability is crucial. Its robust design ensures that it can be integrated into high-availability systems that require continuous operation.

Package and Quality

This Hot Swap Controller is available in a 16-pin narrow SSOP package, providing a compact footprint suitable for space-constrained applications. Linear Technology's commitment to quality ensures that the LTC1421CG#TRPBF meets stringent industry standards for performance and reliability.
