BU4926FVE-TR

Supervisors Overview

The BU4926FVE-TR is a single-channel voltage detector manufactured by Rohm Semiconductor, designed for monitoring power supply integrity in electronic systems. It operates within a wide supply voltage range of 0.7V to 7V and features a fixed under-voltage detection threshold of 2.6V with a precision of ±1%. The device utilizes a VSOF-5 surface-mount package and supports an operating temperature range from -40°C to +125°C. Key electrical characteristics include a reset delay timer of 100µs, low static current consumption of 750nA, and a push-pull CMOS output type that provides active-low reset signals.

Supervisors Feature Summary

• Provides reliable system supervision through a fixed 2.6V detection threshold with high accuracy.
• Features a compact VSOF-5 surface-mount package suitable for space-constrained designs.
• Delivers active-low reset signals via a push-pull CMOS output interface.

Supervisors Applications

• Monitoring battery-powered devices to prevent deep discharge
• Supervising microprocessor and microcontroller power rails
• Ensuring stable operation in portable consumer electronics

Supervisors Procurement Notes

Verify the exact suffix FVE-TR against the manufacturer's latest datasheet to confirm package dimensions and tape-and-reel specifications. Confirm RoHS compliance status and check for any specific environmental declarations required for your region. Ensure the component matches the intended thermal management requirements given the small form factor.

Supervisors Selection Notes

Select this component when a fixed 2.6V threshold is required for single-supply monitoring. Compare its 750nA static current against alternatives if ultra-low power is critical. Verify that the push-pull output capability meets the drive requirements of the downstream logic circuitry without additional pull-up resistors.

Supervisors Part Context

This part belongs to the BU49 series of standard voltage detectors from Rohm Semiconductor. The series offers various fixed thresholds and output configurations. The BU4926FVE-TR specifically targets applications needing a 2.6V trip point in a compact surface-mount package, distinguishing it from adjustable or multi-channel variants within the broader product family.

Supervisors Replacement Considerations

The BD5226G-1 is listed as a similar specification replacement with the same 2.6V threshold. Verify pin compatibility and output stage differences before substitution.
