BD46315G-TR

Overview

The BD46315G-TR is a voltage detector from the BD46 series manufactured by ROHM Semiconductor. It features a fixed detection threshold of 3.1V with ±1% accuracy and a fixed reset delay time of 50ms. The device operates within a supply voltage range of 0.95V to 10V and supports manual reset functionality. It utilizes a CMOS output type and is housed in a 5-pin SSOP package.

Feature Summary

• Provides precise voltage monitoring with a fixed 3.1V detection threshold and high accuracy.
• Includes a fixed 50ms reset delay timer to ensure stable system recovery.
• Supports manual reset input for controlled system initialization.

Applications

• Microprocessor power supply supervision
• Battery-operated equipment voltage monitoring
• Embedded system reset circuitry

Procurement Notes

Verify the specific manufacturing date code and RoHS compliance status upon order confirmation, as availability may vary. Confirm that the 5-SSOP package dimensions match your PCB footprint requirements. Ensure the 3.1V threshold aligns with your target logic voltage levels before finalizing procurement.

Selection Notes

Select this component when a fixed 3.1V threshold and 50ms delay are required. Compare against the BD5231G-1 if adjustable delay or open-drain output is needed instead of CMOS. Verify that the 10V maximum operating voltage suits your system's power rail specifications.

Part Context

This part belongs to the BD46 series of supervisory circuits designed for low-power applications. It shares the 5-SSOP package form factor with other variants in the family but differs in detection voltage and output configuration. It serves as a dedicated voltage monitor for digital logic systems.

Replacement Considerations

The BD5231G-1 is listed as a recommended replacement with the same SSOP5 package. Note that the BD5231G-1 offers an adjustable delay timer and open-drain output, differing from the fixed delay and CMOS output of the BD46315G-TR.
