BD5230G-1TR

Overview

The BD5230G-1TR is a CMOS voltage detector IC from ROHM Semiconductor, featuring a typical threshold voltage of 3.0V and an accuracy of ±0.9%. It operates within a supply voltage range of 0.8V to 6V with a maximum rating of 7V. The device utilizes an open-drain output and includes an adjustable delay timer controlled by an external capacitor. It functions in temperatures from -40°C to +85°C, consuming 0.23µA in the active state and 0.27µA when off.

Feature Summary

• Ultra-low current consumption achieved through CMOS process technology
• Adjustable reset delay time via external capacitor connection
• High detection voltage precision of ±0.9% across operating temperature range

Applications

• Portable electronic devices requiring low power monitoring
• Battery-powered systems needing precise voltage supervision
• General purpose circuit reset generation

Procurement Notes

Verify the specific suffix '1' indicates the N-channel open-drain output configuration. Confirm the 'TR' suffix denotes tape and reel packaging for automated assembly. Ensure the component meets RoHS compliance requirements for your target market. Check for any obsolescence notices or lifecycle status changes directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a fixed 3.0V threshold is required with high accuracy. Choose the adjustable delay feature if system startup sequencing requires a programmable wait period. Consider the SSOP-5 package for space-constrained surface-mount designs. Verify that the 7V maximum supply voltage aligns with the highest expected input rail.

Part Context

This part belongs to the BD52xx series of Nano Energy voltage detectors. It is designed for applications demanding minimal quiescent current. The series offers various threshold voltages from 0.9V to 5.0V in 0.1V increments. The BD5230G-1TR specifically targets the 3.0V detection point within this lineup.
