LT6108HDCB-1#TRMPBF

Overview

The LT6108HDCB-1#TRMPBF is a high-side current sense amplifier with an integrated comparator and precision reference, manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.7V to 60V and draws a typical supply current of 450µA. The device features a maximum input offset voltage of 125µV and a gain error of 0.2%. It includes a latching comparator with a threshold accuracy of ±1.25% and a total propagation delay of typically 1.4µs. The component is specified for operation from –40°C to 125°C and is housed in an 8-lead DFN package.

Feature Summary

• Integrates a precision current sense amplifier with a latching comparator and internal 400mV reference
• Provides fast response capabilities with a 1MHz bandwidth and 500ns step response time
• Features open-drain comparator output for easy system interfacing and level shifting
• Supports wide supply voltage ranges up to 60V with low shutdown current consumption

Applications

• Overcurrent and fault detection in power systems
• Motor control applications requiring fast error detection
• Battery monitoring and management systems
• Industrial control circuits
• Automotive monitoring and control modules

Procurement Notes

Verify the specific suffix TRMPBF indicates tape and reel packaging containing 500 pieces as per official documentation. Confirm the H grade ensures performance across the full industrial temperature range of –40°C to 125°C. Ensure compatibility with the 8-lead DFN footprint during procurement planning.

Selection Notes

Select this component when high-side sensing with integrated protection is required. The latching comparator variant is suitable for applications needing persistent fault flags. Consider the 125µV max offset for high-precision shunt measurements. Verify that the 60V absolute maximum rating aligns with the system's peak voltage conditions.

Part Context

This part belongs to the LT6108 family of high-side current sense amplifiers. The -1 suffix denotes the version with a latching comparator, distinguishing it from the non-latching -2 variant. It shares core amplifier specifications with other family members but offers distinct fault handling characteristics through its integrated latch mechanism.

Replacement Considerations

LT6108IDCB-1#TRMPBF serves as a lower-grade alternative with a restricted operating temperature range of –40°C to 85°C. Verify thermal requirements before substitution. Other family members like LT6108HMS8-1#TRPBF offer MSOP packaging instead of DFN.
