BD46282G-TR

Overview

The BD46282G-TR is a voltage detector IC from ROHM Semiconductor, designed for supervisory circuit applications. It features a fixed under-voltage detection threshold of 2.8V with a precision of ±1%. The device provides a CMOS output type and includes a manual reset function. It operates within a supply voltage range of 0.95V to 10V and has a fixed reset delay time of 200ms. The component supports an operating temperature range from -40°C to +105°C and is housed in an SSOP-5 package.

Feature Summary

• Provides precise under-voltage monitoring with a fixed detection threshold.
• Includes a manual reset capability for controlled system recovery.
• Features a fixed delay timer to ensure stable reset signal generation.
• Utilizes CMOS output interface for digital logic compatibility.

Applications

• Embedded system power supervision
• Microcontroller reset circuitry
• Battery-powered device voltage monitoring

Procurement Notes

Verify the current lifecycle status as the component may be classified as last-time buy or obsolete. Confirm RoHS compliance details through official documentation. Ensure the SSOP-5 package dimensions match the target PCB footprint. Validate that the 2.8V threshold aligns with the specific application requirements before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 2.8V detection threshold is required. The CMOS output and manual reset feature distinguish it from open-drain variants. Consider the 200ms fixed delay for timing-sensitive applications. Compare against the BD5228G-1 series if adjustable delay or different output types are needed. Verify thermal performance within the specified operating temperature range.

Part Context

This part belongs to the BD46 series of voltage detectors from ROHM Semiconductor. It is specifically engineered for low-power supervisory applications requiring high accuracy. The SSOP-5 packaging allows for compact surface-mount integration. The series typically offers various threshold voltages to suit different rail monitoring needs.

Replacement Considerations

The BD5228G-1TR is listed as a recommended replacement with the same SSOP-5 package. Note differences in output type (open drain vs. CMOS) and delay adjustability. Verify electrical parameter compatibility before substitution.
