Overview

The NCV2393DR2G is a dual CMOS comparator designed for low power consumption and wide supply voltage ranges between 2.7V and 16V. It features an extremely low supply current of 6uA typical per channel and a rail-to-rail input common-mode range that includes ground. This AEC-Q100 qualified device is pin-compatible with the industry-standard LM393, making it an ideal upgrade for automotive and industrial power-sensitive applications.

Why Choose This Part

It offers a significant power reduction over bipolar alternatives with a maximum quiescent current of only 15uA across both channels. The high input impedance of 10^12 ohms and low input bias current of 600pA minimize error in high-impedance sensing circuits, while its AEC-Q100 qualification ensures reliability in harsh automotive environments.

Applications

Automotive ECU Monitoring
Used in battery-powered automotive electronic control units where ultra-low standby current is critical for preventing battery drain.
Battery-Powered Threshold Detection
Ideal for portable instrumentation and remote sensors that require high-impedance inputs and long battery life.
Zero-Crossing Detectors
Leverages the common-mode range reaching Vss to detect signals near ground in single-supply systems.
Industrial Limit Switching
Provides reliable voltage monitoring in 12V industrial control loops with high noise immunity and low input bias current.

Getting Started

To evaluate this part, design a PCB layout using the standard SOIC-8 footprint or use a SOIC-to-DIP adapter for breadboarding. Ensure a 0.1uF ceramic bypass capacitor is placed close to the Vcc pin to maintain stability during high-speed transitions, and note that the open-drain output requires a pull-up resistor for proper operation.
