Manufacturer Part Number

BU4221G-TR

Manufacturer

ROHM Semiconductor

Introduction

The ROHM BU4221G-TR is a simple, single-voltage supervisory circuit that monitors the power supply and generates an active-low reset signal when the power supply voltage drops below a preset threshold. It is designed to ensure proper system initialization and operation by providing a well-defined reset signal during power-up and power-down sequences.
