BD5334FVE-TR

Overview

The BD5334FVE-TR is a voltage detector manufactured by ROHM Semiconductor, designed for monitoring single-input power supply lines. It operates within a maximum supply voltage of 10 V and features a threshold detection voltage of 3.4 V with an accuracy of 1%. The device utilizes a CMOS output type and is housed in a VSOF-5 surface-mount package. It supports an adjustable reset delay time and functions reliably across a temperature range from -40°C to +105°C. The component does not include manual reset, watchdog timer, or battery backup switching capabilities.

Feature Summary

• CMOS output interface for digital logic compatibility
• Adjustable reset delay timer functionality
• High precision voltage detection with 1% accuracy

Applications

• Portable electronic devices requiring low-voltage monitoring
• Battery-powered systems needing reliable power supervision
• General-purpose supervisory circuits in consumer electronics

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to discontinued status. Confirm RoHS compliance documentation matches current regulatory requirements. Ensure the VSOF-5 package variant aligns with PCB footprint specifications. Cross-reference datasheet revisions to validate electrical parameters against design constraints before integration.

Selection Notes

Select this component when a fixed 3.4 V threshold with adjustable delay is required in a compact VSOF-5 package. Consider the CMOS output drive capability and 1% accuracy for sensitive applications. Evaluate thermal performance within the -40°C to +105°C operating range. Compare against newer series if long-term availability is critical, as this model is marked for discontinuation.
