BD4948FVE-TR

Overview

The BD4948FVE-TR is a standard voltage detector manufactured by ROHM Semiconductor, designed for monitoring supply voltages in electronic circuits. It features a CMOS output type with a typical under-voltage detection threshold of 4.8V and a precision of ±1%. The device operates within a reset active voltage range of 0.95V to 10V. Key electrical characteristics include a circuit current of 0.60μA when ON and 0.85μA when OFF at VS=4.8V. It utilizes a VSOF5 package and supports RoHS compliance.

Feature Summary

• CMOS output configuration for digital interface compatibility
• High precision voltage detection with ±1% accuracy
• Low power consumption suitable for battery-operated systems
• Compact surface-mount packaging for space-constrained designs

Applications

• Portable electronic devices requiring voltage supervision
• Battery-powered equipment needing low quiescent current
• General-purpose industrial control systems
• Consumer electronics with strict size limitations

Procurement Notes

Verify the obsolete status and last-time-buy availability through official ROHM channels before procurement planning. Confirm that the VSOF5 package dimensions match your PCB footprint requirements. Ensure the CMOS output logic levels are compatible with your target microcontroller or system interface. Check for any specific handling precautions associated with the small outline package during assembly processes.

Selection Notes

Select this component when a precise 4.8V threshold is required with minimal power draw. The CMOS output is preferred over open-drain types for direct logic interfacing without external pull-up resistors. Consider the VSOF5 package if board real estate is limited compared to larger SSOP alternatives. Validate that the operating temperature range meets your environmental specifications.

Part Context

This part belongs to the BD49 series of standard voltage detectors from ROHM Semiconductor. It is positioned as a compact solution for single-channel voltage monitoring applications. The series emphasizes low current consumption and high accuracy, targeting modern portable and industrial electronics where space and power efficiency are critical design constraints.

Replacement Considerations

BD5248G-1 is listed as a similar specification replacement with an open-drain output and SSOP5 package. Verify output drive capabilities and pinout compatibility before substitution.
