LT6108AHMS8-1#TRPBF

Overview

The LT6108AHMS8-1#TRPBF is a high-side current sense amplifier with an integrated precision voltage reference and a latching comparator. It operates within a supply voltage range of 2.7V to 60V and consumes 450µA of supply current. The device features a maximum input offset voltage of 125µV, a gain error of 0.2% maximum, and a signal bandwidth of 1MHz. The internal comparator has a threshold of 400mV with a total threshold error of ±1.25%. It is specified for operation from –40°C to 125°C.

Feature Summary

• Integrates a precision current sense amplifier, a 400mV internal voltage reference, and a latching comparator in a single device.
• Provides fast response capabilities with a typical propagation delay of 1.4µs and a step response time of 500ns for critical fault detection.
• Features an open-drain comparator output that allows easy interfacing with various system components and digital supplies.
• Supports wide supply ranges up to 60V with low shutdown current consumption for power-sensitive applications.

Applications

• Current shunt measurement
• Motor control systems
• Battery monitoring
• Automotive monitoring and control
• Industrial control

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the 'H' grade designation corresponds to the extended temperature range of –40°C to 125°C. Ensure compatibility with the 8-lead MSOP package dimensions for PCB layout. Cross-reference the manufacturer's latest documentation for any updates on lead-free finishing or marking codes.

Selection Notes

Select this component for applications requiring high-side current sensing with integrated overcurrent protection. The latching comparator variant is suitable for scenarios where fault states must be captured and held until reset. Consider the external resistor requirements for setting gain and comparator thresholds. Evaluate thermal management needs given the operating temperature range and package type.

Part Context

This part belongs to the LT6108 family of high-side current sense amplifiers. The LT6108-1 variant specifically includes a latching comparator, distinguishing it from the non-latching LT6108-2. The AH grade denotes higher precision specifications compared to standard grades. The MS8 package provides a compact footprint for space-constrained designs.

Replacement Considerations

LT6108AHMS8-1#PBF (Same electrical characteristics and functionality; differs only in shipping container format as tray instead of tape and reel).
