BD4825FVE-TR

Overview

The BD4825FVE-TR is a standard voltage detector manufactured by Rohm Semiconductor, designed for monitoring single-channel supply voltages. It features an open-drain output and provides a low-active reset signal. The device operates within a detection voltage range of 0.7V to 7V, with a typical under-voltage detection threshold of 2.5V and a precision of ±1%. It supports a maximum supply voltage of 7V and functions across an industrial temperature range of -40°C to 125°C. The IC consumes minimal current, drawing 0.40μA in the ON state and 0.55μA in the OFF state at VDET=4.8V. It utilizes a VSOF5 package.

Feature Summary

• Provides precise under-voltage detection with adjustable active voltage range
