BD4925FVE-TR

Overview

The BD4925FVE-TR is a CMOS standard voltage detector manufactured by ROHM Semiconductor, designed for monitoring supply voltages in electronic circuits. It features a typical under-voltage detection threshold of 2.5V with a precision of ±1%. The device operates within a reset active voltage range of 0.95V to 10V and utilizes a CMOS output type. Key electrical characteristics include a circuit current of 0.60μA (ON) and 0.85μA (OFF) at Vs=4.8V, with a hysteresis voltage defined as Vs x 0.05. It supports low-level output currents of 0.4mA and high-level currents of 2mA, functioning reliably across an operating temperature range from -40°C to +105°C.

Feature Summary

• CMOS process technology ensures low power consumption and high accuracy voltage detection.
• Integrated hysteresis function prevents output oscillation during voltage transitions near the threshold.
• Compact VSOF-5 package design facilitates space-constrained surface-mount applications.

Applications

• Portable battery-powered devices requiring precise voltage monitoring
• Microprocessor system reset circuits
• General-purpose supervisory logic in consumer electronics

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm datasheet revisions match specific production batches. Ensure storage conditions comply with moisture sensitivity levels for surface-mount devices. Validate pinout compatibility with existing PCB footprints before integration into new designs.

Selection Notes

Select this component when a fixed 2.5V threshold with CMOS output is required. Consider the ±1% precision and hysteresis specifications for noise immunity needs. Evaluate the VSOF-5 package dimensions against board space constraints. Compare static current values against other family members if ultra-low power is critical.

Part Context

This part belongs to the BD49 series of standard voltage detectors from ROHM Semiconductor. It serves as a specialized supervisor IC for single-input voltage monitoring. The device complements other variants in the lineup offering different thresholds or output types, providing a dedicated solution for 2.5V detection scenarios in industrial and commercial applications.

Replacement Considerations

BD5225G-1 is listed as a recommended replacement with similar specifications. Note differences in package type (SSOP-5 vs VSOF-5) and output structure (Open Drain vs CMOS). Verify electrical parameter alignment and mechanical fit before substitution.
