BD46265G-TR

Overview

The BD46265G-TR is a voltage detector IC from the BD46 series by ROHM Semiconductor, housed in an SSOP-5 package. It features a fixed detection threshold of 2.6 V with ±1% accuracy and a fixed reset delay time of 50 ms. The device supports a supply voltage range of 0.95 V to 10 V and offers CMOS output. It includes manual reset functionality without a watchdog timer or battery backup switch. Operating temperatures range from -40°C to +105°C.

Feature Summary

• Provides precise voltage monitoring with a fixed 2.6 V threshold and high accuracy.
• Features a fixed 50 ms reset delay time for stable system initialization.
• Supports manual reset input for controlled system recovery.

Applications

• Embedded systems requiring reliable power-on reset sequences
• Microcontroller supervision in industrial environments
• Portable electronic devices with strict voltage monitoring needs

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance and package integrity upon receipt. Cross-reference datasheet specifications against current design requirements before integration. Ensure storage conditions meet semiconductor handling standards to prevent degradation.

Selection Notes

Select this component when a fixed 2.6 V threshold and CMOS output are required. Consider the BD5226G-1 as a recommended replacement if adjustable delay or open-drain output is preferred. Evaluate thermal performance within the specified operating temperature range during design phase.

Part Context

Part of the BD46 series supervisory circuits designed for general-purpose voltage monitoring. Manufactured by ROHM Semiconductor using CMOS technology. The BD46265G-TR variant specifically targets applications needing fixed delay times and manual reset capabilities.

Replacement Considerations

BD5226G-1TR is listed as a recommended replacement with similar package dimensions but offers adjustable delay and open-drain output instead of fixed delay and CMOS output.
