BU4841G-TR

Supervisors Overview

The BU4841G-TR is a CMOS voltage detector IC manufactured by ROHM Semiconductor, designed for monitoring single power supply lines. It features an open-drain output and operates within a supply voltage range of 0.7 V to 7 V. The device detects under-voltage conditions with a typical threshold of 4.1 V and maintains a precision of ±1%. It consumes a maximum operating current of 550 nA and functions reliably across a temperature range of -40°C to +125°C. Packaged in an SSOP-5 format, it lacks manual reset, watchdog timer, or chip enable functionalities.

Supervisors Feature Summary

• CMOS technology ensures low power consumption suitable for battery-operated systems
• Open-drain output configuration allows flexible interfacing with various logic families
• High accuracy detection threshold minimizes false triggering during voltage fluctuations

Supervisors Applications

• Microprocessor system reset circuits
• Portable electronic device power management
• Industrial control board supervision

Supervisors Procurement Notes

Verify component authenticity through authorized distributors as the part status is obsolete. Confirm package integrity upon receipt since the item may have been stored for extended periods. Check datasheet revisions to ensure compatibility with current design requirements before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 4.1 V threshold is required for single-input voltage monitoring. Consider the SSOP-5 package constraints for PCB layout. Evaluate alternative parts if manual reset or watchdog features are necessary, as this specific model does not support those functions.

Supervisors Part Context

This component belongs to the BU4841G series of standard voltage detectors. It shares specifications with similar parts like BD5241G-1 but differs in packaging and availability status. The series is characterized by high precision and low standby current, targeting applications where power efficiency and reliable reset generation are critical.
