BU4834G-TR

Supervisors Overview

The BU4834G-TR is a CMOS voltage detector IC manufactured by ROHM Semiconductor, designed for monitoring single power supply rails. It features an open-drain output and operates within a supply voltage range of 0.7 V to 7 V. The device provides a typical under-voltage detection threshold of 3.4 V with a precision of ±1%. It lacks manual reset, watchdog timer, or battery backup switch functions. The component supports surface-mount installation in an SSOP-5 package and operates across a temperature range of -40°C to +125°C.

Supervisors Feature Summary

• CMOS technology ensures low power consumption during operation.
• Open-drain output configuration allows flexible interfacing with various logic levels.
• High accuracy voltage detection with specified tolerance for reliable system supervision.

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Battery-operated equipment needing under-voltage protection
• General-purpose supervisory circuits in consumer electronics

Supervisors Procurement Notes

Verify the specific suffix and packaging details against official datasheets before procurement. Confirm that the NRND status aligns with long-term production requirements. Ensure compatibility with existing PCB footprints and thermal management strategies. Cross-reference RoHS compliance documentation for regulatory adherence. Validate operating temperature ranges against final application environments.

Supervisors Selection Notes

Select this component when a fixed 3.4 V threshold is required for single-input monitoring. Consider the open-drain output capability for level shifting needs. Evaluate the low standby current for battery-sensitive applications. Assess the SSOP-5 package constraints for space-limited designs. Compare against alternative thresholds if system voltage varies significantly.

Supervisors Part Context

This part belongs to the BU483x series of standard voltage detectors from ROHM. It shares architectural similarities with other members like BU4830G and BU4836G, differing primarily in the detection threshold voltage. The series is characterized by compact packaging and low quiescent current, targeting cost-sensitive and space-constrained embedded systems.

Supervisors Replacement Considerations

The BD5234G-1 is listed as a similar level replacement with the same package type. Verify electrical parameter equivalence, particularly the 3.4 V threshold and output characteristics, before substitution.
