LT6109AIMS-2#TRPBF

Overview

The LT6109AIMS-2#TRPBF is a high-side current sense amplifier with integrated reference and comparators, manufactured by Analog Devices Inc. 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% maximum. The device includes two comparators with the same polarity configuration, a 400mV precision internal reference, and open-drain outputs. It is specified for operation from –40°C to 85°C and is housed in a 10-lead MSOP package.

Feature Summary

• Integrates a precision current sense amplifier with an internal 400mV voltage reference and two comparators configured with the same polarity.
• Provides fast response capabilities with a typical propagation delay of 1.4µs and a signal bandwidth of 1MHz for critical error detection.
• Features open-drain comparator outputs that allow easy interface to system components and support latching functionality for capturing high-speed events.

Applications

• Overcurrent, undercurrent, 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 AIMS variant meets the required –40°C to 85°C operating temperature range for your application environment. Ensure compatibility with the 10-lead MSOP footprint during PCB layout.

Selection Notes

Select this component for applications requiring high-side sensing with integrated fault protection. The LT6109-2 version is suitable where both comparators share the same polarity. Consider the 125µV max offset for low-current accuracy needs and verify the 60V common-mode voltage capability matches the system power rails.

Part Context

This part belongs to the LT6109 family of high-side current sense amplifiers. It is functionally similar to the LT6109AIMS-2#PBF but differs in packaging format. The device integrates level-shifting, amplification, and comparison functions into a single compact solution for industrial and automotive monitoring.
