LT6700HDCB-1#TRPBF

Overview

The LT6700HDCB-1#TRPBF is a micropower, low voltage dual comparator with an internal 400mV reference housed in a 6-lead DFN package. It operates on supply voltages from 1.4V to 18V and draws approximately 6.5µA at 5V. The device features open-collector outputs capable of sinking over 5mA, allowing load references up to 18V independent of the supply. Input bias current is typically ±10nA, and hysteresis is internally set to approximately 6.5mV.

Feature Summary

• Integrates two comparators with a fixed 400mV internal reference for simplified threshold detection.
• Features one inverting and one noninverting external input configuration suitable for window comparator applications.
• Open-collector outputs enable level translation by allowing the output load to be referenced to any voltage up to 18V.
• Includes internal hysteresis to ensure stable output operation against noisy input signals.

Applications

• Battery-powered system monitoring
• Threshold detectors
• Window comparators
• Relay driving
• Industrial control systems

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the DCB package variant matches the required footprint. Ensure the -1 designation aligns with the necessary input polarity configuration for the design. Check for automotive grade requirements if operating in harsh environments.

Selection Notes

Select this part when a low quiescent current comparator with a fixed reference is required. The -1 suffix provides mixed input polarities ideal for window sensing. Consider the LT6700HV variants if input or output voltages exceed 18V. Verify that the open-collector output interface meets the downstream logic requirements.

Part Context

This component belongs to the LT6700 family of micropower comparators. It shares core electrical characteristics with the LT6700IS6-1 and LT6700HS6-1 but utilizes a DFN package instead of TSOT-23. The family offers various temperature grades and input configurations to suit different environmental and circuit topology needs.
