LT6108AIMS8-2#PBF

Overview

The LT6108AIMS8-2#PBF is a high-side current sense amplifier with an integrated comparator and reference, housed in an 8-lead MSOP package. It operates within a supply voltage range of 2.7V to 60V and draws 450µA typical supply current. The device features a maximum input offset voltage of 125µV and a gain error of 0.2% maximum. It includes a non-latching open-drain comparator output with a total threshold error of ±1.25%. The component is specified for operation from –40°C to 85°C.

Feature Summary

• Integrates a precision current sense amplifier with a user-configurable gain via external resistors.
• Includes an internal 400mV precision reference and a non-latching comparator for fault detection.
• Provides direct access to amplifier and comparator inputs and outputs for system integration.

Applications

• Overcurrent and fault detection
• Current shunt measurement
• Motor control
• Industrial control

Procurement Notes

Verify the specific suffix 'AIMS8-2' matches the required temperature grade (–40°C to 85°C) and non-latching comparator configuration. Confirm the MSOP package type aligns with board layout constraints. Ensure compatibility with the intended supply voltage range up to 60V. Cross-reference the manufacturer's latest documentation for any updates to pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this part when a high-side sensing solution with integrated fault protection is required. The A-grade variant ensures tighter offset voltage specifications compared to standard grades. The non-latching comparator option suits applications requiring continuous monitoring without manual reset. Consider the thermal performance of the MSOP package if operating near the upper temperature limits.

Part Context

This component belongs to the LT6108 family of high-side current sense amplifiers. The -2 suffix denotes the version with a non-latching comparator, distinguishing it from the -1 version which features a latching comparator. The AIM prefix indicates the industrial temperature grade (-40°C to 85°C). The MS8 suffix specifies the 8-lead plastic MSOP package.

Replacement Considerations

LT6108IMS8-2#PBF offers similar functionality with standard grade specifications. LT6108AHMS8-2#PBF provides the same non-latching comparator but with an extended temperature range up to 125°C. Verify that substitute parts maintain the same pinout and electrical characteristics for direct replacement.
