BU4827G-TR

Supervisors Overview

The BU4827G-TR is a single-channel CMOS voltage detector manufactured by ROHM Semiconductor, designed for supervising power supply voltages in electronic circuits. It operates within a supply voltage range of 1.2 V to 10 V and features a fixed threshold detection voltage of 2.7 V with an accuracy of ±1%. The device utilizes an open-drain output type and provides a reset delay time of 100 µs. It functions without manual reset or watchdog timer capabilities. The component is housed in a compact SSOP-5 package, suitable for surface mount technology applications.

Supervisors Feature Summary

• CMOS technology ensures low power consumption for battery-operated systems
• Fixed threshold voltage detection for precise power monitoring
• Open-drain output configuration for flexible interfacing

Supervisors Applications

• Portable electronic devices requiring voltage supervision
• Battery-powered equipment needing power management
• General-purpose circuit protection systems

Supervisors Procurement Notes

Verify the specific suffix and packaging variant against official datasheets before procurement, as distribution channels may list obsolete or discontinued status. Confirm RoHS compliance details directly from the manufacturer's documentation. Ensure the SSOP-5 package dimensions match your PCB footprint requirements. Check for any regional sales restrictions or availability limitations that may affect sourcing timelines.

Supervisors Selection Notes

Select this component when a fixed 2.7 V threshold is required for system reset or monitoring. Consider the open-drain output compatibility with your microcontroller logic levels. Evaluate the 100 µs reset delay against your system's startup timing requirements. Verify that the operating temperature range meets your environmental conditions. Compare static current consumption with alternative detectors if power efficiency is critical.
