LTC4242CUHF#PBF

Hot Swap Controllers Overview

The LTC4242CUHF#PBF is a six-channel hot swap controller designed for PCI Express applications. It operates with a supply voltage range of 2.7V to 14.4V and draws 1.6mA of supply current. The device features internal switches for both high-side and low-side control, housed in a 38-WFQFN exposed pad package measuring 5x7mm. It supports automatic retry, current limiting, fault timeout, thermal limiting, and UVLO functions within an operating temperature range of -40°C to 85°C.

Hot Swap Controllers Feature Summary

• Integrates six independent channels for managing multiple power rails simultaneously
• Includes programmable soft-start and current limit controls for safe insertion
• Provides comprehensive protection against overcurrent, overtemperature, and undervoltage conditions

Hot Swap Controllers Applications

• PCI Express backplane systems
• Multi-rail server power distribution
• Industrial equipment requiring safe board insertion

Hot Swap Controllers Procurement Notes

Verify the specific suffix matches the required temperature grade and packaging format. Confirm RoHS compliance status and lead times directly with authorized distributors or Analog Devices Inc. prior to ordering. Ensure the component meets all environmental regulations applicable to your region.

Hot Swap Controllers Selection Notes

Select this controller when designing systems requiring simultaneous management of multiple power domains. Verify that the input voltage range aligns with the system's available power rails. Consider the thermal performance requirements given the integrated switch architecture and package size.

Hot Swap Controllers Part Context
