LTC1645IS8#TRPBF

Hot Swap Controllers Overview

The LTC1645IS8#TRPBF is a dual-channel hot swap controller designed for positive low-voltage applications. It operates with an external N-channel MOSFET and supports supply voltages from 1.2V to 12V. The device features a typical circuit breaker threshold voltage of 50mV and requires an external sense resistor. It is housed in an 8-pin SOIC package, suitable for surface mount mounting, and functions within a commercial temperature range of 0°C to 70°C.

Hot Swap Controllers Feature Summary

• Dual-channel architecture for independent control of two power rails
• Integrated sequence generator for controlled power-up timing
• External FET configuration allows selection of optimal switching devices
• Built-in fault protection mechanisms including overcurrent and thermal shutdown

Hot Swap Controllers Applications

• PCI Express card edge connectors
• Hot-swappable backplane systems
• Peripheral board insertion management
• Multi-rail power distribution units

Hot Swap Controllers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing. Confirm that the IS8 variant corresponds to the industrial or commercial grade temperature rating required by your design specifications. Ensure compatibility with the 8-pin SOIC footprint during PCB layout finalization.

Hot Swap Controllers Selection Notes

Select this component when dual-channel hot swap functionality is required for low-voltage systems. It is appropriate for designs needing precise current limiting via external resistors. Consider the 8-pin SOIC package constraints and the necessity for external MOSFETs when evaluating space and bill of materials costs.

Hot Swap Controllers Part Context

This part belongs to the LTC1645 family of hot swap controllers manufactured by Analog Devices. It shares functional similarities with other members like the LTC1645CS8 but differs in package type and temperature range. The series is widely used in telecommunications and computing infrastructure for safe board insertion.

Hot Swap Controllers Replacement Considerations

Direct substitutes include the LTC1645CS8#TRPBF for similar functionality in a different package. The LTC1645IS#PBF offers comparable features in a 14-pin SOIC format. Verify pinout compatibility before substituting.
