Overview

The TLV7031DBVR is a single-channel, micro-power comparator featuring a rail-to-rail common-mode input voltage range and a push-pull output stage. It is designed for low-voltage operation down to 1.6V with an extremely low quiescent current of 335 nA, making it ideal for battery-critical monitoring applications.

Why Choose This Part

This comparator offers a significant power-to-performance ratio with 335 nA typical supply current and no phase reversal for overdriven inputs. Its integrated hysteresis and rail-to-rail capability reduce external component count and PCB footprint in SOT-23-5 packaging.

Applications

Battery Monitoring
Ultra-low power consumption allows for continuous voltage threshold monitoring in portable devices without significant battery drain.
Threshold Detectors
Integrated 17mV hysteresis provides clean switching in noise-prone environments like gas and smoke detectors.
Zero-Crossing Detection
Rail-to-rail inputs and high-speed response (3us propagation delay) enable efficient signal edge detection in low-speed switching power systems.
Level Translation
The push-pull output simplifies interfacing between different logic voltage domains in space-constrained mobile electronics.

Getting Started

To evaluate this part, use a standard SOT-23-5 breakout board or the TLV7031EVM evaluation module. Ensure a 0.1uF bypass capacitor is placed close to the VDD pin (1.6V to 6.5V) to minimize noise and maintain stability during high-speed transitions.
