BD4930FVE-TR

Overview

The BD4930FVE-TR is a single-channel voltage detector manufactured by ROHM Semiconductor, designed for supervisory circuit applications. It operates within a supply voltage range of up to 10 V and features a threshold voltage of 3 V with an accuracy of ±1%. The device utilizes a CMOS output type with a reset delay time of 100 µs and lacks manual reset or watchdog timer functions. It is housed in a VSOF-5 surface-mount package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• CMOS output interface for digital logic compatibility
• Single input channel for dedicated voltage monitoring
• Compact VSOF-5 surface-mount packaging

Applications

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

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance documentation matches specific manufacturing batches. Validate package marking against official datasheet specifications to prevent counterfeit substitution during procurement processes.

Selection Notes

Select this component when a fixed 3 V threshold is required for systems operating below 10 V. Ensure the CMOS push-pull output aligns with downstream logic requirements. Consider thermal management within the specified -40°C to +105°C ambient range for reliable operation in industrial environments.

Part Context

This part belongs to the BD49 series of standard voltage detectors from ROHM Semiconductor. It serves as a specialized supervisory IC within the PMIC category, focusing on simple voltage monitoring without complex timing features. The VSOF-5 package allows for space-constrained PCB layouts compared to larger traditional packages.
