BD4926FVE-TR

Overview

The BD4926FVE-TR is a CMOS voltage detector IC from the BD49 series manufactured by ROHM Semiconductor. It features a detection threshold voltage of 2.6 V with an accuracy of ±1%. The device operates within a supply voltage range up to 10 V and provides a CMOS output type. It includes a fixed reset delay time of 100 µs and lacks manual reset, watchdog timer, or battery backup switch functions. The component is housed in a VSOF-5 package and supports surface mount installation.

Feature Summary

• CMOS output interface for digital logic compatibility
• Fixed 100 µs reset delay timing mechanism
• Single-channel under-voltage monitoring capability

Applications

• Microprocessor system power supervision
• Battery-operated device voltage monitoring
• Embedded system reset circuit generation

Procurement Notes

Verify end-of-life status as the component is marked as discontinued. Confirm availability through authorized distributors or secondary markets. Check RoHS compliance documentation for environmental standards. Validate package integrity upon receipt. Ensure static-sensitive handling procedures are followed during storage and assembly.

Selection Notes

Select this part when a fixed 2.6 V threshold is required for single-supply monitoring. Consider the VSOF-5 package for space-constrained PCB layouts. Evaluate the 100 µs delay against system startup requirements. Compare static current consumption if low-power operation is critical. Verify compatibility with downstream CMOS logic levels.

Part Context

This component belongs to the BD49 standard voltage detector family. It serves as a dedicated supervisory circuit for monitoring power rails in electronic systems. The device integrates precision reference and comparator circuits on a single CMOS chip. It replaces older discrete solutions for voltage detection tasks.
