LTC4261IGN-2#TRPBF

Hot Swap Controllers Overview

The LTC4261IGN-2#TRPBF is a hot swap voltage controller manufactured by Analog Devices Inc., designed for negative voltage applications. It operates within a supply voltage range of -12 V to -100 V and features adjustable current limiting. The device integrates an analog-to-digital converter (ADC) and I2C monitoring capabilities, housed in a 28-SSOP surface-mount package. It supports programmable features including automatic retry, fault timeout, lockout fault protection, overvoltage protection (OVP), and undervoltage lockout (UVLO). The component functions as a single-channel controller with a typical operating supply current of 2 mA.

Hot Swap Controllers Feature Summary

• Integrates an internal ADC and I2C interface for precise system monitoring and control
• Supports negative voltage hot swap operations up to -100 V
• Includes programmable protection mechanisms such as OVP, UVLO, and fault lockout

Hot Swap Controllers Applications

• -48V telecommunications systems
• Industrial backplane power distribution
• Negative voltage server chassis management

Hot Swap Controllers Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing. Confirm that the IGN variant meets the required industrial temperature range specifications for your application environment. Ensure compatibility with negative voltage rails during integration. Check current availability status as supply may be restricted or limited for this specific part number.

Hot Swap Controllers Selection Notes

Select this component for designs requiring robust protection on negative voltage rails with digital monitoring needs. The integrated ADC allows for detailed telemetry without external sensors. Consider the 28-SSOP package size for board space constraints. Verify that the adjustable current limit settings align with the load requirements and cable ratings.
