BD5258G-TR

Overview

The BD5258G-TR is a CMOS voltage detector manufactured by ROHM Semiconductor, designed for monitoring power supply voltages in electronic circuits. It features an adjustable delay timer and operates within a supply voltage range of 0.95V to 10V. The typical under-voltage detection threshold is 5.8V with a precision of ±1%. The device provides an open-drain output that goes low during reset conditions. It functions reliably across a temperature range of -40°C to 105°C and is housed in a compact SSOP5 package.

Feature Summary

• Adjustable delay timer functionality for customized reset timing
• Open-drain output configuration for flexible interfacing
• High accuracy voltage detection with ±1% precision
• Wide operating voltage range supporting various system requirements

Applications

• Power supply supervision in embedded systems
• Microcontroller reset circuit generation
• Battery-powered device voltage monitoring
• Industrial control system protection

Procurement Notes

Verify the specific ordering suffix and packaging details against official ROHM documentation before procurement. Confirm that the component meets all required environmental standards and operational specifications for your application. Ensure compatibility with existing design constraints regarding package type and electrical parameters.

Selection Notes

Select this component when a precise voltage threshold near 5.8V is required with adjustable delay capabilities. Consider the open-drain output requirement and the SSOP5 package size for space-constrained designs. Evaluate the operating temperature range to ensure suitability for the intended environmental conditions.

Part Context

This part belongs to the BD52xx series of voltage detectors from ROHM Semiconductor. These components are designed for reliable power management in consumer and industrial electronics. The series offers various detection voltages and package options to suit different application needs while maintaining high accuracy and low power consumption characteristics.

Replacement Considerations

The BD5250G-1TR is a recommended replacement with the same pinout and package. Note that it has a typical detection voltage of 5.0V compared to the BD5258G's 5.8V. Verify that the lower threshold meets your system requirements before substituting.
