LT6119IMS-1#TRPBF

Overview

The LT6119IMS-1#TRPBF is a high-side current sense device from Analog Devices, featuring a precision amplifier, 400mV reference, and two latching comparators. It operates on a 2.7V to 60V supply with 550µA current consumption. The amplifier offers 200µV max offset and 0.2% gain error. Comparators provide ±1.25% threshold accuracy with power-on reset. It supports fast fault detection in –40°C to 85°C environments within a 10-lead MSOP package.

Feature Summary

• Integrated high-side current sensing with low offset voltage and configurable gain
• Dual latching comparators with internal 400mV reference and power-on reset capability
• Fast propagation delay for rapid overcurrent and undercurrent event detection
• Wide supply range supporting industrial and automotive monitoring applications

Applications

• Overcurrent and undercurrent protection circuits
• Battery monitoring systems
• Motor control applications
• Automotive monitoring and control
• Industrial control systems

Procurement Notes

Verify the IMS-1 suffix indicates the specific comparator polarity configuration required for your design. Confirm the temperature grade meets your operational environment limits. Check for RoHS compliance status and lead-free finish specifications before finalizing procurement. Ensure the tape and reel packaging aligns with your assembly equipment capabilities.

Selection Notes

Select this component when high-side sensing with integrated fault detection is needed. The IMS-1 variant provides opposing polarity comparators suitable for distinct warning and disconnect thresholds. Consider the 10-lead MSOP package for space-constrained designs. Evaluate external resistor tolerance requirements to maintain specified gain accuracy.

Part Context

This part belongs to the LT6119 family of complete high-side current sense devices. It integrates an amplifier, reference, and comparators into a single chip. The IMS-1 designation specifies the industrial temperature range and the -1 polarity configuration for the internal comparators.

Replacement Considerations

LT6119HMS-1#TRPBF offers the same functionality but with an extended operating temperature range up to 125°C.

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 them connected in the same polarity.

How is the comparator latch functionality controlled?

The latch is enabled or disabled via the LE (Latch Enable) pin. When high, the output latches low upon tripping; when low, it functions transparently.
