Overview
The LT6703HVIS5-3#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 a noninverting input, open-collector output capable of sinking over 5mA, and built-in hysteresis for stable operation. It is housed in a 5-lead TSOT-23 package and specified for temperatures from -40°C to 85°C.
Feature Summary
- Integrates a 400mV internal reference with a micropower comparator
- Features Over-The-Top input and output ranges independent of supply voltage
- Includes built-in hysteresis to ensure noise immunity and stable switching
- Open-collector output supports level translation across different voltage domains
Applications
- Battery-powered system monitoring
- Threshold detectors
- Window comparators
- Relay driving circuits
- Automotive monitor and controls
Procurement Notes
Verify the specific suffix TRMPBF indicates mini tape and reel packaging containing 500 pieces. Confirm the VIS5 designation corresponds to the industrial temperature range of -40°C to 85°C and the HV variant capabilities. Ensure the ordering code matches the required lead frame finish and RoHS compliance status before finalizing procurement orders.
Selection Notes
Select this component when a fixed 400mV threshold is required for low-voltage monitoring applications. The noninverting input configuration distinguishes it from the LT6703-2 variant. Consider the wide input voltage range up to 36V for high-side sensing or level shifting tasks where standard comparators may fail due to supply limitations.
Part Context
This part belongs to the LT6703 family of micropower comparators designed for battery-operated systems. It combines low power consumption with high input voltage tolerance. The series includes variants with different input polarities and temperature grades, all sharing the core architecture of a 400mV reference-based comparator.

FAQ
What is the polarity of the external input on the LT6703HVIS5-3?
The LT6703-3 variant features a noninverting external input, while the other comparator input is internally connected to the 400mV reference.
Can the output voltage exceed the supply voltage?
Yes, the open-collector output can be referred to any voltage up to 18V (or 36V for HV versions) independent of the supply voltage used.
