LTC4241CGN#PBF

Hot Swap Controllers Overview

The LTC4241CGN#PBF is a hot-swap controller designed for safe insertion and removal of circuit boards from live PCI bus slots. It integrates a primary controller managing four PCI power rails and an independent auxiliary controller for the 3.3V supply. The device utilizes external N-channel transistors for positive voltage control and internal switches for negative voltages, featuring adjustable ramp rates, foldback current limiting, and fault indication outputs.

Hot Swap Controllers Feature Summary

• Integrates primary and independent auxiliary controllers for multi-rail power management
• Provides adjustable power-on ramp rates for controlled voltage sequencing
• Includes foldback current limiting to suppress short-circuit current spikes
• Features high-side drivers for external N-channel FETs and internal switches for negative rails

Hot Swap Controllers Applications

• PCI-based server systems
• Computer systems requiring hot-pluggable modules
• Circuits requiring safe board insertion into live PCI slots

Hot Swap Controllers Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and temperature range. Ensure compatibility with target PCI bus voltage levels and current requirements. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents before procurement.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring robust protection for multiple PCI power rails during hot-swap operations. Consider the integrated auxiliary controller for simplified 3.3V management. Evaluate the need for adjustable ramp rates and foldback current limiting features relative to system load characteristics and fault tolerance requirements.

Hot Swap Controllers Part Context

This part belongs to the LTC4241 family of hot-swap controllers manufactured by Analog Devices Inc.
