Overview
The LT6703HDC-2#TRMPBF 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 specified for operation from -40°C to 125°C and housed in a 3-lead DFN package.
Feature Summary
- Integrates a 400mV reference with an inverting comparator input
- Operates with wide supply range from 1.4V to 18V
- Features open-collector output for level translation
- Includes internal hysteresis for stable noise rejection
Applications
- Battery-powered system monitoring
- Threshold detectors
- Window comparators
- Relay driving
- Industrial control systems
Procurement Notes
Verify the specific suffix DC indicates the commercial temperature grade variant within the H-series family structure. Confirm the TRMPBF designation corresponds to the mini tape and reel packaging format. Ensure the part number matches the required inverting input polarity configuration for the design.
Selection Notes
Select this component when an inverting comparator response is required alongside a fixed 400mV threshold. The wide input voltage range allows operation independent of the supply rail. Verify that the open-collector output interface aligns with the downstream logic or load requirements.
Part Context
This part belongs to the LT6703 series of micropower comparators. It shares architectural similarities with the LT6703-3 but utilizes an inverting input configuration. The H-series designation denotes extended industrial and automotive temperature capabilities compared to standard commercial variants.

FAQ
What is the polarity of the external input?
The LT6703HDC-2 features an inverting external input, while the other comparator input is internally connected to the 400mV reference.
Can the output handle voltages higher than the supply?
Yes, the open-collector output can be referred to any voltage up to 18V independent of the supply voltage.
