LT6119IMS-2#TRPBF

Overview

The LT6119IMS-2#TRPBF is a high-side current sense device from Analog Devices, packaged in a 10-lead MSOP. It integrates a precision current sense amplifier, an internal 400mV reference, and two latching comparators configured with the same polarity. The device operates on a supply voltage range of 2.7V to 60V with a typical supply current of 550µA. It features a maximum input offset voltage of 200µV, a gain error of 0.2% maximum, and a signal bandwidth of 1MHz. The total threshold error for the comparators is ±1.25% maximum.

Feature Summary

• Integrates a precision current sense amplifier with low offset voltage and high common-mode rejection ratio.
• Includes two latching comparators with power-on reset capability and fast response time.
• Features an internal 400mV precision reference for setting comparator thresholds.
• Supports wide supply voltage operation suitable for industrial and automotive environments.

Applications

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

Procurement Notes

Verify the specific IMS-2 suffix indicates the dual-inverting comparator configuration. Confirm the TRPBF suffix denotes tape and reel packaging. Ensure the component meets the -40°C to 85°C operating temperature range requirements for your application environment.

Selection Notes

Select this part when a high-side solution with integrated fault protection is required. The LT6119-2 variant is appropriate when both comparators must trigger on the same condition. Consider the 1MHz bandwidth for applications requiring rapid error detection in critical systems like motor control.

Part Context

This component belongs to the LT6119 family of current sense amplifiers. It is designed to replace discrete solutions by combining sensing, referencing, and comparison functions into a single small package. The device simplifies board layout by reducing the number of external components needed for robust current monitoring.

FAQ

What is the difference between the LT6119-1 and LT6119-2 versions?

The LT6119-1 has comparators connected in opposing polarity, while the LT6119-2 has both comparators connected in the same polarity.

How is the comparator latch functionality controlled?

The LE (Latch Enable) pin controls the latch. When high, the latch is enabled; when low, it is disabled.
