LTC4260ISW#TRPBF

Hot Swap Controllers Overview

The LTC4260ISW#TRPBF is a hot swap controller manufactured by Analog Devices Inc., designed for safe insertion and removal of live circuit boards. It operates within an input voltage range of 8.5 V to 80 V and features adjustable current limiting, overvoltage protection, and undervoltage lockout. The device supports I2C communication for configuration and monitoring. It is housed in a 24-SOIC surface-mount package and is rated for industrial operating temperatures from -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Enables safe insertion and removal of live circuit boards without power disruption or damage
• Provides programmable current limiting and slew rate control to manage inrush currents
• Includes comprehensive fault protection with automatic retry and latch-off capabilities
• Offers digital interface via I2C for real-time status monitoring and parameter adjustment

Hot Swap Controllers Applications

• Telecommunications equipment requiring hot-swappable modules
• Industrial automation systems with modular architecture
• Data center infrastructure supporting live board replacement
• Test and measurement instruments needing safe power cycling

Hot Swap Controllers Procurement Notes

Verify the suffix TRPBF indicates tape-and-reel packaging and lead-free compliance. Confirm the ISW variant meets industrial temperature specifications (-40°C to +85°C). Ensure the order matches the exact part number to avoid confusion with tube-packaged equivalents like LTC4260CSW#PBF. Check for RoHS3 compliance documentation if required by regional regulations.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring robust hot-swap functionality with digital control. The I2C interface allows for flexible configuration of current limits and fault responses. Consider the 24-SOIC package size for PCB layout constraints. Verify that the 80 V maximum input voltage aligns with the system's power supply rails. Evaluate thermal performance based on expected load currents and ambient conditions.

Hot Swap Controllers Part Context

The LTC4260 belongs to Analog Devices' family of hot swap controllers, which are essential for maintaining system availability during maintenance. This specific model integrates precise current sensing and protection logic into a compact package. It complements other PMIC solutions by handling high-voltage insertion events safely. The series is widely used in applications where board replacement must occur without shutting down the entire system.

Hot Swap Controllers Replacement Considerations

LTC4260CSW#PBF offers identical functionality but in tube packaging instead of tape-and-reel. LTC4260CGN#PBF provides similar features in an SSOP-24 package. Verify pin compatibility and thermal characteristics before substituting. No direct functional upgrades are available within the same package type.
