BU4810G-TR

Supervisors Overview

The BU4810G-TR is a CMOS voltage detector manufactured by ROHM Semiconductor, designed for monitoring single-input power supply lines. It operates within a supply voltage range of 0.7 V to 7 V and features a fixed under-voltage detection threshold of 1.0 V with ±1% accuracy. The device utilizes an open-drain output configuration and lacks manual reset or watchdog timer functions. It supports surface-mount installation in an SSOP-5 package, ensuring reliable performance across an extended industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• CMOS technology enables ultra-low power consumption suitable for battery-operated systems
• High precision voltage detection ensures accurate system supervision
• Open-drain output allows flexible interfacing with various logic families

Supervisors Applications

• Portable electronic devices requiring low standby current
• Industrial control systems needing wide temperature operation
• Consumer electronics utilizing single-supply architectures

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to the Not Recommended for New Designs (NRND) status. Confirm that the SSOP-5 package dimensions match existing PCB footprints. Ensure compliance with RoHS directives if required by specific regional regulations. Validate electrical parameters against latest official datasheets before final integration.

Supervisors Selection Notes

Select this component when a fixed 1.0 V threshold is required for single-channel monitoring. Consider the open-drain output compatibility with downstream circuitry. Evaluate the trade-off between the NRND status and long-term availability needs. Compare static current specifications against other family members if lower power is critical.

Supervisors Part Context

This part belongs to the BU48xxG series of standard voltage detectors. It shares the SSOP-5 package and general operational characteristics with variants like BU4817G-TR and BU4828G-TR, differing primarily in their specific detection thresholds. The series is characterized by low current consumption and high accuracy.

Supervisors Replacement Considerations

BD5210G-1 is documented as a recommended replacement with the same package and similar specification level.
