LTC4260CSW#TRPBF

Hot Swap Controllers Overview

The LTC4260CSW#TRPBF is a hot-swap voltage controller manufactured by Analog Devices Inc., designed for high-availability systems. It operates within an input voltage range of 8.5 V to 80 V and features adjustable current limiting. The device supports I2C communication for configuration and monitoring, including programmable fault timeouts, overvoltage protection, and automatic retry capabilities. Packaged in a 24-SOIC surface-mount format, it consumes 2 mA of supply current and functions reliably across a temperature range of 0°C to +70°C.

Hot Swap Controllers Feature Summary

• I2C-compatible interface for digital control and status reporting
• Adjustable current limit with programmable fault timeout and lockout
• Integrated overvoltage protection and undervoltage lockout
• Supports automatic retry functionality after fault clearance

Hot Swap Controllers Applications

• Hot-swap controllers on plug-in cards for server backplanes
• High-availability system power management modules
• General-purpose hot-swap voltage control applications

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'TRPBF' against official Analog Devices documentation to confirm tape-and-reel packaging versus tube variants. Ensure the component meets RoHS3 compliance requirements for your assembly process. Cross-reference the 24-SOIC package dimensions with your PCB footprint library to guarantee mechanical compatibility before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this controller when designing systems requiring precise thermal ramp-up and adjustable current limiting for hot-swap scenarios. The I2C interface allows for flexible configuration of protection thresholds. Consider the 24-SOIC package size and operating temperature range relative to your enclosure constraints. This part is suitable for applications needing robust fault handling without internal switching elements.

Hot Swap Controllers Part Context

This component belongs to the LTC4260 series of hot-swap voltage controllers from Analog Devices. It is distinct from integrated power switch ICs like the LTC4269 or LTC4210, as it functions primarily as a controller rather than a combined switch-controller unit. The series is widely used in telecommunications and industrial computing infrastructure for safe board insertion and removal.
