LTC4241IGN#TRPBF

Hot Swap Controllers Overview

The LTC4241IGN#TRPBF is a hot-swap controller designed for safe insertion and removal of boards from live PCI bus slots. It features a primary controller managing four PCI power supplies and an independent auxiliary controller for the 3.3V auxiliary supply. The device operates within a supply voltage range of 2.7V to 14.4V, with a quiescent current of 1.6mA. It supports adjustable current limiting, fault timeout, thermal limiting, and undervoltage lockout (UVLO). Packaged in a 28-lead SSOP, it functions reliably across an operating temperature range of -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Integrates primary control for four PCI power rails alongside an independent auxiliary controller for 3.3V support
• Provides comprehensive protection mechanisms including adjustable current limiting, fault timeout, and thermal limiting
• Ensures safe board insertion and removal from live PCI bus environments through controlled power sequencing

Hot Swap Controllers Applications

• PCI bus board insertion and removal systems
• Multi-rail PCI power distribution management
• Auxiliary 3.3V power supply control in PCI architectures

Hot Swap Controllers Procurement Notes

Verify the specific suffix IGN against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with PCI bus electrical requirements before integration. Confirm availability status as distribution data may vary. Cross-reference pinouts with the latest datasheet to prevent design errors during PCB layout.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring simultaneous management of multiple PCI power rails and an auxiliary supply. It is suitable for applications needing robust protection against overcurrent and thermal faults during hot-swap operations. Consider the SSOP package constraints and operating temperature range relative to the target environment.

Hot Swap Controllers Part Context

This part belongs to the LTC4241 series of hot-swap controllers by Analog Devices. It is specifically engineered for PCI bus applications, distinguishing itself by combining primary multi-rail control with dedicated auxiliary power management. This integration simplifies system design by reducing the component count required for complex power sequencing and protection tasks.

Hot Swap Controllers Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Generic hot-swap controllers may not match the specific multi-rail and auxiliary integration of the LTC4241.
