Overview

The TLV1702AIDGKR is a dual-channel, general-purpose comparator designed for wide supply range operation from 2.2V to 36V. It features an open-collector output and rail-to-rail inputs, making it highly versatile for interfacing with different logic levels. With a low quiescent current of 55uA per comparator, it is optimized for power-sensitive monitoring applications.

Why Choose This Part

The device offers a high maximum supply voltage of 36V while maintaining a low current consumption of 75uA maximum. Its open-collector output simplifies level shifting, allowing the output to be pulled up to a different voltage rail than the comparator supply. Additionally, the 560ns propagation delay ensures rapid response times for fault detection circuits.

Applications

Overvoltage and Undervoltage Detection
Used in power supply monitoring to trigger system alerts or shutdowns when rail voltages exceed or fall below set thresholds.
Window Comparators
The dual-channel configuration allows for easy implementation of window detectors to ensure signals stay within a specific voltage range.
Zero-Crossing Detectors
Utilizes the high-voltage capability and rail-to-rail input to detect when an AC signal crosses the ground or a reference point.
Industrial Sensor Interfacing
Converts analog sensor outputs into digital signals for microcontrollers in 12V or 24V industrial systems.

Getting Started

To evaluate this part, use a standard 8-pin VSSOP to DIP adapter for breadboarding or prototype on a universal PCB. Ensure a pull-up resistor is placed on the output pins, as the open-collector architecture cannot drive high without one. Decouple the V+ pin with a 0.1uF ceramic capacitor placed close to the device to minimize switching noise.
