Overview
The LT6703CDC-2#TRPBF is a micropower, low voltage comparator with an internal 400mV reference. It operates on a single supply from 1.4V to 18V and draws 6.5µA typical quiescent current. The device features an inverting input, open-collector output capable of sinking over 5mA, and built-in hysteresis. It is housed in a 3-lead DFN package and specified for commercial temperature range.
Feature Summary
- Integrates a 400mV reference with an inverting comparator input
- Provides stable operation via internal hysteresis
- Supports level translation through open-collector output
- Enables Over-The-Top input operation independent of supply voltage
Applications
- Battery-powered system monitoring
- Threshold detectors
- Window comparators
- Relay driving
- Industrial control systems
Procurement Notes
Verify the specific ordering suffix matches the required tape and reel packaging configuration. Confirm the component meets RoHS compliance standards for the intended manufacturing process. Ensure the commercial temperature grade aligns with the operational environment requirements before finalizing procurement orders.
Selection Notes
Select this part when a fixed low-voltage threshold detection is required without external reference components. The inverting polarity suits applications where the signal must trigger below the reference level. Consider the DFN package dimensions for space-constrained PCB layouts requiring surface mount assembly.
Part Context
This component belongs to the LT6703 series of micropower comparators. It shares functional similarities with the LT6703-3 variant but differs by utilizing an inverting input configuration instead of noninverting. The series is designed for low-power battery monitoring and general-purpose threshold detection tasks.

FAQ
What is the function of the external input pin?
The external input serves as the inverting terminal for the comparator, allowing the user to monitor voltages against the internal 400mV reference.
How does the output stage handle high voltage loads?
The open-collector output allows the load to be referred to any voltage up to 18V independent of the supply voltage, facilitating level translation.
