LT6703HDC-3#TRPBF

Overview

The LT6703HDC-3#TRPBF is a micropower, low voltage comparator featuring an internal 400mV reference. It operates on a single supply from 1.4V to 18V with a typical quiescent current of 6.5μA at 5V. The device utilizes a noninverting input configuration and provides an open-collector output capable of sinking over 5mA. It is housed in a 3-lead (2mm × 2mm) plastic DFN package and supports an industrial temperature range of –40°C to 85°C.

Feature Summary

Integrates a 400mV internal reference for precise threshold detection without external components.
Features Over-The-Top input capability allowing operation up to 18V regardless of the supply voltage.
Includes built-in hysteresis to ensure stable operation and noise immunity.
Open-collector output allows level translation and connection to loads independent of the supply rail.

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 H grade corresponds to the required industrial temperature range of –40°C to 85°C for your application environment. Ensure the DC package footprint matches your PCB layout constraints. Cross-reference the manufacturer's latest documentation for any updates regarding lead-free compliance or pinout definitions.

Selection Notes

Select this component when a fixed 400mV threshold is required for low-voltage monitoring. The noninverting input polarity suits applications where the signal rises above the reference to trigger the output. Consider the HV variant if input voltages exceed 18V. Verify that the open-collector output interface aligns with the downstream logic requirements.

Part Context

This part belongs to the LT6703 family of micropower comparators. It shares architectural similarities with the LT6703-2 but differs in input polarity. The DC package offers a compact solution compared to larger SOT-23 options. It complements other Linear Technology analog devices designed for battery management and portable instrumentation.
