Overview

The LM2903FVT-E2 is a dual-channel, general-purpose voltage comparator from Rohm Semiconductor designed to operate from a wide range of supply voltages. This open-collector device is capable of handling single-supply operation from 3V to 32V and is housed in a space-saving 8-TSSOP-B package.

Why Choose This Part

The device offers excellent versatility with a wide supply range of 3V to 32V and an extended operating temperature range of -40 to 125 degrees Celsius. Its open-collector output allows for easy wired-OR configurations, while the dual-element design in a small TSSOP footprint maximizes PCB space efficiency.

Applications

Limit Comparators
Used in monitoring circuits to detect when a signal exceeds or falls below a specific reference voltage.
Logic Level Translation
Leveraging the open-collector output to interface between different logic voltage domains, such as 3.3V to 5V systems.
Zero-Crossing Detectors
Utilizing the dual comparator elements to identify the zero-voltage points in AC signal processing.
Battery Voltage Monitoring
Ideal for low-battery detection in portable equipment due to its wide operating voltage range and low quiescent current.
