LT6108IDCB-2

Overview

The LT6108IDCB-2 is a high-side current sense amplifier with an integrated precision reference and non-latching comparator. It operates on a supply voltage range of 2.7V to 60V with a typical supply current of 450µA. The device features a maximum input offset voltage of 125µV, a bandwidth of 1MHz, and a step response time of 500ns. The comparator threshold is set by an internal 400mV reference with a total threshold error of ±1.25%. It is housed in an 8-lead DFN package and specified for operation from –40°C to 85°C.

Feature Summary

• Integrates a precision current sense amplifier, a 400mV internal voltage reference, and a non-latching open-drain comparator within a single device.
• Provides fast fault detection capabilities with a total propagation delay of typically 1.4µs and a 500ns step response time for critical overcurrent protection.
• Features low offset voltage and gain error specifications to ensure accurate current monitoring across a wide dynamic range.

Applications

• Overcurrent and fault detection in power systems
• Motor control applications requiring fast error detection
• Battery monitoring and management systems

Procurement Notes

Verify the specific suffix IDCB-2 corresponds to the non-latching comparator variant in the 8-lead DFN package. Confirm the temperature grade 'I' indicates the –40°C to 85°C operating range. Ensure compatibility with the required supply voltage range up to 60V and check for any lead-free finish requirements if applicable to the manufacturing batch.

Selection Notes

Select this component when a combined sensing and comparison function is required without external discrete comparators. The non-latching output is suitable for transient fault handling where automatic recovery is needed. Consider the 125µV max offset for high-precision shunt measurements and verify that the 60V common mode range meets the system's power rail requirements.

Part Context

This part belongs to the LT6108 family of high-side current sense amplifiers. The -2 suffix designates the version with a non-latching comparator, distinguishing it from the -1 variant which includes latching functionality. The IDCB package identifies the 8-lead plastic DFN form factor with industrial temperature grading.
