Overview
The LT6703HDC-2#TRPBF is a micropower, low voltage analog 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 3-lead DFN package and provides an inverting input configuration. It includes built-in hysteresis for stable operation and features an open-collector output capable of sinking over 5mA. The component supports Over-The-Top inputs and outputs up to 18V independent of the supply voltage.
Feature Summary
- Integrates a precise 400mV internal reference with a micropower comparator circuit
- Provides stable threshold detection through built-in hysteresis
- Supports wide supply ranges while maintaining ultra-low power consumption
- Enables level translation via open-collector output independent of supply rail
Applications
- Battery-powered system monitoring
- Threshold detectors
- Window comparators
- Relay driving circuits
- Automotive monitor and controls
Procurement Notes
Verify the specific ordering suffix matches the required temperature grade and packaging format. Confirm that the DC package variant corresponds to the intended PCB footprint. Ensure the inverting input polarity aligns with the circuit design requirements. Check for any lead-free or RoHS compliance documentation if mandated by the project specifications.
Selection Notes
Select this component when a fixed low-voltage threshold is required without external resistor networks. The inverting input configuration suits applications where the signal must trigger below the reference level. Consider the thermal performance of the DFN package for high ambient temperatures. Evaluate the propagation delay characteristics against the speed requirements of the target application.
Part Context
This part belongs to the LT6703 family of micropower comparators. It shares core electrical characteristics with the LT6703-3 but differs in input polarity. The 'H' designation indicates an extended industrial temperature range capability. The 'DC' suffix specifies the 2mm x 2mm DFN package form factor used for space-constrained designs.

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 compare an external voltage against the internal 400mV reference.
How does the output stage handle voltages higher than the supply?
The open-collector output allows the load to be referred to any voltage up to 18V, independent of the VS supply voltage, enabling level translation capabilities.
