BU4229FVE-TR

Overview

The BU4229FVE-TR is a single-channel voltage detector manufactured by Rohm Semiconductor, designed for supervisory circuit applications. It operates within a supply voltage range of 0.8V to 6V and features an adjustable reset delay timer with a low-active output state. The device utilizes an open-drain output type and is housed in a compact VSOF5 package. It supports surface-mount installation and functions reliably across a wide temperature range from -40°C to +125°C.

Feature Summary

Provides simple reset or power-on reset functionality with an adjustable delay timer.
Features an open-drain output compatible with various logic families.
Operates effectively within a broad industrial temperature range.

Applications

Microprocessor system supervision
Portable equipment power management
Battery-powered device monitoring

Procurement Notes

Verify the specific threshold voltage requirements against the official datasheet, as the BU4229 variant typically corresponds to a 2.9V detection level. Confirm package compatibility with the VSOF5 footprint. Check current availability status, as this component may be subject to end-of-life restrictions or discontinuation notices from the manufacturer.

Selection Notes

Select this component when a fixed threshold voltage near 2.9V is required for single-supply monitoring. Ensure the design accommodates the open-drain output configuration and external pull-up resistor needs. Verify that the adjustable delay feature meets timing requirements without additional external components beyond those specified in the reference design.

Part Context

This part belongs to the BU42xx series of voltage detectors from Rohm Semiconductor. These devices are engineered for low-power consumption and high accuracy in portable and battery-operated systems. The series offers various threshold options to suit different supply rail voltages.
