Overview
The LT6703IDC-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 configuration with the other input tied internally to the reference. It provides an open-collector output capable of sinking over 5mA, allowing level translation up to 18V independent of the supply voltage. The component is housed in a 3-lead DFN package.
Feature Summary
- Integrates a 400mV reference with an inverting comparator input for simplified threshold detection
- Features wide supply range operation from 1.4V to 18V with micropower consumption
- Includes built-in hysteresis to ensure stable operation against input noise
- Open-collector output supports level translation to voltages up to 18V
Applications
- Battery-powered system monitoring
- Threshold detectors
- Window comparators
- Relay driving
- Industrial control systems
Procurement Notes
Verify the specific suffix #TRMPBF or #TRPBF matches the required tape and reel quantity. Confirm the temperature grade 'I' corresponds to the –40°C to 85°C operating range. Ensure the DC package variant aligns with PCB footprint requirements. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and lead times.
Selection Notes
Select this part when an inverting comparator response is required relative to a fixed 400mV threshold. Choose the IDC package for surface mount applications requiring a small footprint. Consider the LT6703HV variants if input or output voltages exceed 18V. Verify that the 6.5µA supply current meets the power budget constraints of the design.
Part Context
This component belongs to the LT6703 family of micropower comparators. It shares architectural similarities with the LT6703-3 (noninverting) and LT6703HV series (high voltage). The ID suffix denotes the industrial temperature grade, distinguishing it from commercial or high-temperature variants within the same product line.
Replacement Considerations
LT6703IDC-3#TRMPBF offers the same electrical characteristics but with a noninverting input polarity instead of inverting.
