LT6108HDCB-1#TRPBF

Overview

The LT6108HDCB-1#TRPBF is a high-side current sense amplifier with an integrated comparator and reference, housed in an 8-lead DFN package. It operates within a supply voltage range of 2.7V to 60V and draws 450µA of supply current. The device features a maximum input offset voltage of 350µV and a gain error of -0.3%. It includes a latching comparator with a typical propagation delay of 1.4µs and a signal bandwidth of 1MHz.

Feature Summary

• Integrates a precision current sense amplifier with a latching comparator and internal voltage reference
• Provides direct access to amplifier and comparator inputs and outputs for flexible system configuration
• Features fast response times suitable for detecting overcurrent conditions in critical applications

Applications

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

Procurement Notes

Verify the specific ordering suffix matches the required temperature grade and package variant. Confirm that the DCB package designation aligns with your PCB footprint requirements. Ensure compatibility with the latching comparator function specified for the '-1' version. Cross-reference the datasheet electrical characteristics against your system's voltage and current constraints before finalizing procurement.

Selection Notes

Select this component when high-side sensing with integrated fault protection is required. The latching comparator option is ideal for capturing transient overcurrent events that require manual reset. Consider the thermal performance of the exposed pad connection for high-voltage applications. Evaluate external resistor values to optimize gain and ensure output accuracy within the specified dynamic range.

Part Context

This part belongs to the LT6108 family of high-side current sense amplifiers. It is distinguished by its integration of a comparator and reference, eliminating the need for external components for basic fault detection. The H-grade variant ensures operation across the extended industrial temperature range, making it suitable for demanding environments.
