Overview

The NCV2901DTBR2G is an automotive-qualified quad differential comparator designed for wide supply range operation between 3V and 36V. It features four independent comparators with open-collector outputs that allow for easy level shifting and wired-OR logic configurations in harsh electrical environments.

Why Choose This Part

This device is AEC-Q100 qualified and PPAP capable, ensuring high reliability for automotive safety systems. Its open-collector output stage is compatible with TTL, DTL, and CMOS logic, while the common-mode input range includes ground even when operated from a single supply.

Applications

Automotive Sensor Interfacing
Used to convert analog sensor signals into digital logic for ECUs in powertrain and body electronics.
Over-Voltage Detection
Monitoring battery rails in 12V and 24V vehicle systems to trigger protection circuits when voltage exceeds safe limits.
Zero-Crossing Detectors
Utilizing high input impedance and low bias current for timing and synchronization in motor control and power conversion.
Window Comparators
Combining multiple elements to detect when a signal is within a specific voltage range for diagnostic monitoring.

Getting Started

Designers should ensure a pull-up resistor is connected to the output pin to establish the logic high level. When prototyping, bypass capacitors should be placed as close to the Vcc pin as possible to mitigate noise in high-speed switching applications.

Also Consider

NCV2903 ONonsemi - A dual-channel version for applications requiring fewer comparators in a smaller SOIC-8 footprint.
