LT6108IDCB-1#TRPBF

Overview

The LT6108IDCB-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 supports temperatures from –40°C to 85°C. The device features a maximum input offset voltage of 350µV, a gain error of 0.2% maximum, and a signal bandwidth of 1MHz. Supply current is typically 450µA, reducing to 5µA maximum in shutdown mode.

Feature Summary

• Integrates a precision current sense amplifier with a latching comparator and internal 400mV reference
• Provides direct access to amplifier and comparator inputs and outputs for flexible system configuration
• Features fast response times suitable for critical overcurrent detection and motor control applications

Applications

• Current shunt measurement
• Overcurrent and fault detection
• Motor control systems
• Battery monitoring
• Industrial control circuits

Procurement Notes

Verify the specific ordering suffix matches the required temperature grade and package type. Confirm that the #TRPBF designation corresponds to the tape and reel packaging format intended for automated assembly processes. Ensure compatibility with the target application's voltage and thermal requirements before finalizing procurement.

Selection Notes

Select this component when high-side sensing is required with integrated fault protection capabilities. The IDCB variant offers a compact footprint suitable for space-constrained designs. Consider the latching comparator feature if persistent fault signaling is necessary without continuous monitoring overhead.

Part Context

This part belongs to the LT6108 family of high-side current sense amplifiers. It shares core functionality with other variants but differs in package style and temperature rating. The DFN package provides improved thermal performance compared to MSOP options, making it suitable for dense PCB layouts.
