BD4831FVE-TR

Overview

The BD4831FVE-TR is a CMOS voltage detector manufactured by ROHM Semiconductor, designed for monitoring single-input supply voltages. It features an open-drain output and operates within a maximum supply voltage of 10 V. The device provides a typical threshold voltage of 3.1 V with 1% accuracy and includes a fixed reset delay time of 100 µs. It lacks manual reset, watchdog timer, or battery backup functions. Operating temperatures range from -40°C to +105°C, and it is housed in a VSOF-5 surface-mount package.

Feature Summary

• CMOS technology enables low power consumption for efficient voltage supervision.
• Open-drain output interface allows flexible connection to various logic systems.
