BU4915G-TR

Supervisors Overview

The BU4915G-TR is a standard voltage detector manufactured by ROHM Semiconductor, designed for monitoring power supply voltages in electronic circuits. It operates within a supply voltage range of 0.7 V to 7 V and features a typical under-voltage detection threshold of 1.5 V with a precision of ±1%. The device utilizes a CMOS output type that is active low, without a reset delay timer or manual reset function. It is housed in an SSOP-5 package (2.9x2.8 mm) and supports an operating temperature range from -40°C to 125°C. Circuit current consumption is specified at 0.40 μA (ON) and 0.55 μA (OFF) at VDET=4.8V, with hysteresis set at VDET x 0.05.

Supervisors Feature Summary

• CMOS output interface with low-active state logic
• High detection accuracy with ±1% precision tolerance
• Wide operating temperature range suitable for industrial environments
• Compact SSOP-5 surface mount packaging

Supervisors Applications

• Microprocessor power supply monitoring
• Portable battery-powered equipment supervision
• Test and measurement instrument voltage tracking
• Multi-output power supply regulation

Supervisors Procurement Notes

Verify component authenticity through authorized distributors due to the Not Recommended for New Designs status. Confirm RoHS compliance and SSOP-5 package integrity upon receipt. Cross-reference ordering part numbers against official ROHM documentation to ensure correct variant selection. Check for obsolescence notices before finalizing procurement plans.

Supervisors Selection Notes

Select this component for legacy system maintenance where existing designs utilize the BU4915G architecture. Evaluate replacement options such as the BD5250G-1 if new design implementation is required, noting differences in detection voltage and output configuration. Ensure the 1.5 V threshold aligns with target circuit requirements.

Supervisors Part Context

The BU4915G belongs to ROHM's standard voltage detector series, intended for supervisory applications in consumer and industrial electronics. It provides reliable voltage monitoring with minimal current consumption. The specific BU4915G-TR variant indicates tape-and-reel packaging for automated assembly processes.

Supervisors Replacement Considerations

The BD5250G-1 is identified as a recommended replacement with the same SSOP-5 package. Note that the substitute offers different detection voltages and adjustable delay features.
