BU4810FVE-TR

Supervisors Overview

The BU4810FVE-TR is a standard voltage detector manufactured by ROHM Semiconductor, designed for monitoring single-channel supply voltages. It features an open-drain output and operates within a detection voltage range of 0.7 V to 7 V. The typical under-voltage detection threshold is set at 1.0 V with a precision of ±1%. The device supports a reset active state that is low and includes hysteresis defined as VDET multiplied by 0.05. It functions reliably across a temperature range from -40°C to 125°C.

Supervisors Feature Summary

• Provides reliable power-supply supervision through precise under-voltage detection capabilities.
• Features an open-drain output structure suitable for interfacing with various logic families.
• Incorporates internal hysteresis to prevent output oscillation during voltage transitions.

Supervisors Applications

• Portable electronic devices requiring low-power voltage monitoring
• Battery-operated equipment needing under-voltage protection
• General-purpose industrial control systems
