LT6108HDCB-2#TRMPBF

Overview

The LT6108HDCB-2#TRMPBF is a high-side current sense amplifier with an integrated comparator and reference, housed in an 8-lead DFN package. It operates on a supply voltage range of 2.7V to 60V with a typical supply current of 450µA. The device features a maximum input offset voltage of 125µV and a gain error of 0.2%. The internal comparator has a threshold accuracy of ±1.25% and a non-latching output. It functions within a temperature range of –40°C to 125°C.

Feature Summary

• Integrates a precision current sense amplifier with a user-configurable gain setting via external resistors.
• Includes an internal 400mV precision voltage reference for accurate comparator thresholding.
• Features a fast-response open-drain comparator with a non-latching output configuration.
• Provides direct access to amplifier inputs and outputs for flexible system integration.

Applications

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

Procurement Notes

Verify the specific suffix #TRMPBF indicates a mini tape and reel packaging format containing 500 pieces. Confirm the 'H' grade designation corresponds to the extended industrial temperature range of –40°C to 125°C. Ensure the DCB package type matches the required PCB footprint dimensions of 2mm by 3mm. Cross-reference the manufacturer part number against official Analog Devices documentation to validate authenticity.

Selection Notes

Select this component when a compact solution combining amplification and protection logic is required. The non-latching comparator variant is suitable for applications requiring immediate reset upon fault clearance. Consider the 1MHz bandwidth for high-speed error detection needs. Evaluate the 125µV maximum offset voltage against the minimum detectable current requirements of the specific application design.

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 identifier specifies the 8-lead plastic DFN package form factor. This series is designed for industrial and automotive environments requiring robust fault handling capabilities.
