LT6108HDCB-2#TRPBF

Overview

The LT6108HDCB-2#TRPBF is a high-side current sense amplifier with an integrated comparator and reference, housed in an 8-lead DFN package. It operates within a supply voltage range of 2.7V to 60V and features a maximum input offset voltage of 125µV and a gain error of 0.2%. The device includes a non-latching open-drain comparator output with a typical propagation delay of 1.4µs and a built-in 400mV precision reference. It functions across a temperature range of –40°C to 125°C with a typical supply current of 450µA.

Feature Summary

• Integrates a precision current sense amplifier with a user-configurable gain setting via external resistors.
• Includes a non-latching comparator with a fixed internal 400mV threshold for overcurrent detection.
• Provides direct access to amplifier inputs and outputs for flexible system integration.
• Features low shutdown current capability for power-sensitive applications.

Applications

• Overcurrent and fault detection
• Current shunt measurement
• Motor control
• Battery monitoring

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the H grade designation matches the required industrial temperature range of –40°C to 125°C. Ensure the DCB package type aligns with PCB footprint requirements. Cross-reference the manufacturer part number against official Analog Devices documentation to validate authenticity and revision status.

Selection Notes

Select this component for high-side sensing where space is constrained by the small DFN package. Choose the -2 variant specifically for non-latching comparator behavior. Evaluate the 125µV offset and 0.2% gain error against system accuracy needs. Consider the 60V maximum supply voltage limit for high-voltage bus monitoring applications.

Part Context

This device belongs to the LT6108 family of high-side current sense amplifiers. The -2 suffix denotes the version equipped with a non-latching comparator, distinguishing it from the latching -1 variant. The HDCB suffix identifies the 8-lead (2mm × 3mm) plastic DFN package format.
