Overview

The TLV1702AIRUGR is a dual-channel, micro-power comparator featuring an open-collector output and a wide supply range from 2.2V to 36V. It is designed for low power consumption, drawing only 55uA of quiescent current per channel, while maintaining a maximum propagation delay of 560ns. The device includes rail-to-rail inputs and internal phase-reversal protection to ensure stable operation in demanding signal environments.

Why Choose This Part

This comparator offers extreme flexibility with a 36V maximum input voltage and an ultra-small 1.5mm x 1.5mm X2QFN package for space-constrained designs. It eliminates common design issues with integrated phase-reversal protection and handles high-voltage transients better than typical low-voltage comparators.

Applications

Overvoltage and Undervoltage Detectors
Utilizing the wide 36V supply range to monitor industrial power rails for fault conditions.
Window Comparators
Configuring the dual channels to detect if a signal remains within a specific voltage threshold range.
Level Translation
The open-collector output allows for easy interfacing between different logic levels, such as 1.8V, 3.3V, and 5V systems.
Battery Powered Monitoring
Leveraging the 55uA low-power profile to extend battery life in portable sensing applications.

Getting Started

When designing with the open-collector output, ensure a pull-up resistor is selected based on the desired logic level and the 20mA output current capability. For prototyping, use a SMT-to-DIP adapter for the 8-X2QFN package or evaluate performance using TI Universal Op-Amp Evaluation Modules (EVMs).
