BU4330G-TR

Overview

The BU4330G-TR is a CMOS low voltage detector manufactured by ROHM Semiconductor. It functions as a supervisory circuit designed to monitor power supply voltages and generate reset signals when thresholds are breached. The component operates within a specified temperature range and utilizes an SSOP5 package for surface mount installation. This device is classified as Not Recommended for New Designs (NRND) by the manufacturer, indicating it is intended for existing production support rather than new product development.

Feature Summary

• CMOS technology implementation for low voltage detection
• Supervisory circuit functionality for power monitoring
• Surface mount SSOP5 package configuration

Applications

• Existing electronic equipment requiring voltage supervision
• Legacy system maintenance and repair
• Power supply monitoring circuits in established designs

Procurement Notes

Verify current availability status before procurement planning. The BU4330G-TR carries a Not Recommended for New Designs (NRND) lifecycle status from ROHM Semiconductor. Sourcing should focus on replacement of existing inventory or specific legacy requirements. Confirm end-of-life timelines with authorized distributors to ensure sufficient supply for ongoing maintenance needs without committing to new design implementations.

Selection Notes

This component is suitable only for retrofitting or maintaining existing systems where the BU4330G-TR was originally specified. Engineers designing new products should select alternative recommended parts from the ROHM portfolio. Ensure compatibility with the required voltage threshold and package constraints if substituting into older schematics. Review the official datasheet for electrical characteristics relevant to the specific application environment.

Part Context

The BU4330G-TR belongs to the BU4330 series of CMOS low voltage detectors produced by ROHM Semiconductor. These devices are part of a broader family of power supply support circuits designed for monitoring input voltages. The series typically includes variants with different detection thresholds and delay times, packaged in compact formats suitable for space-constrained printed circuit board layouts.
