LTC4242CUHF#TRPBF

Hot Swap Controllers Overview

The LTC4242CUHF#TRPBF is a six-channel hot swap controller designed for PCI Express applications. It integrates N-channel power switches with a supply voltage range of 2.7V to 14.4V and operates within a commercial temperature range of 0°C to 70°C. The device features programmable auto-retry, current limiting, latched fault handling, and slew rate control. Packaged in a 38-pin QFN with an exposed pad, it supports surface-mount installation.

Hot Swap Controllers Feature Summary

• Integrates six independent channels for high-density power distribution
• Supports PCI Express standard hot insertion requirements
• Provides programmable protection against overcurrent and thermal faults

Hot Swap Controllers Applications

• PCI Express backplane systems
• High-density server power distribution units
• Industrial I/O card power management

Hot Swap Controllers Procurement Notes

Verify the suffix TRPBF indicates tape-and-reel packaging and lead-free compliance. Confirm the CUHF variant meets commercial temperature specifications rather than industrial ranges. Ensure the 38-QFN footprint matches the target PCB layout. Cross-reference the manufacturer datasheet for exact electrical tolerances before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this component when designing multi-lane PCI Express interfaces requiring integrated switching. The six-channel architecture reduces bill-of-materials count compared to discrete solutions. Verify that the 2.7V to 14.4V input range aligns with the system bus voltage. Consider the 38-QFN package size constraints during mechanical design integration.

Hot Swap Controllers Part Context

This part belongs to the Analog Devices Power by Linear hot swap controller family. It complements other channel-count variants like the LTC4240 and LTC4241. The series focuses on simplifying hot insertion protection for high-speed digital interfaces. It serves as a core power management element in expansion chassis designs.

Hot Swap Controllers Replacement Considerations

Direct substitutes include the LTC4242IUHF#PBF for extended temperature operation or the LTC4242CUHF#PBF for tube packaging. Verify pinout compatibility and thermal performance when swapping between these variants.
