LT6700MPDCB-1#TRM

Overview

The LT6700MPDCB-1#TRM is a micropower, low voltage dual comparator with an internal 400mV reference. It operates on supplies from 1.4V to 18V and draws 5.7µA at 1.4V. The device features open-collector outputs capable of sinking up to 5mA. Input bias current is ±10nA max. Propagation delay is 18µs (high-to-low) and 29µs (low-to-high). It is housed in a 6-lead DFN package and specified for -55°C to 125°C.

Feature Summary

• Integrates two comparators with a fixed 400mV internal reference
• Open-collector outputs allow level translation independent of supply voltage
• Includes internal hysteresis to ensure stable output operation
• Supports over-the-top input voltages up to 36V

Applications

• Battery-powered system monitoring
• Threshold detectors
• Window comparators
• Relay driving
• Automotive monitor and controls

Procurement Notes

Verify the specific suffix #TRM indicates tape and reel packaging containing 500 pieces. Confirm the MP grade corresponds to the extended -55°C to 125°C temperature range. Ensure the DCB package matches the required footprint. Check for AEC-Q100 qualification if automotive use is intended.

Selection Notes

Select this variant when one inverting and one non-inverting input are required for window comparator functions. Choose the MP grade for extreme temperature environments. Verify that the 400mV reference threshold aligns with the application requirements. Consider the open-collector output for interfacing with different logic levels.

Part Context

This component belongs to the LT6700 family of micropower comparators. It shares architectural similarities with the LT6700HV but lacks the higher voltage rating. The MPDCB designation specifies the military/extended industrial temperature grade and the DFN package type. Other variants include CS, IS, and HS grades with narrower temperature ranges.

Replacement Considerations

LT6700IDCB-1#TRPBF offers similar functionality with a -40°C to 85°C range. LT6700HDCB-1#TRMPBF provides a -40°C to 125°C range. LT6700CDCB-1#TRMPBF is suitable for commercial applications from 0°C to 70°C. All share the same pinout and electrical characteristics within their respective temperature limits.
