BD4741G-TR

Overview

The BD4741G-TR is a standard voltage detector manufactured by ROHM Semiconductor, designed for supervisory circuit applications. It operates within a supply voltage range of 0.85 V to 10 V and features an under-voltage detection threshold of 4.1 V with ±1% precision. The component utilizes an open-collector output type and lacks manual reset or watchdog timer functionalities. It is housed in an SSOP-5 package and supports operation across a temperature range of -40°C to +75°C.

Feature Summary

• Provides fixed under-voltage detection at a specific threshold level
• Features open-collector output configuration for system monitoring
• Operates without manual reset or watchdog timer capabilities

Applications

• System power supply monitoring
• Microcontroller reset circuit generation
• Battery voltage supervision

Procurement Notes

Verify current availability status as the component may be subject to discontinuation or last-time-buy restrictions. Confirm RoHS compliance details through official documentation before integration. Ensure design-in compatibility with existing SSOP-5 footprints and electrical requirements.

Selection Notes

Select this component when a fixed 4.1 V detection threshold is required without manual reset functionality. Consider the open-collector output interface for compatibility with pull-up resistor networks. Evaluate thermal performance within the specified -40°C to +75°C operating range for target application environments.

Part Context

This part belongs to the BD47 series of standard voltage detectors from ROHM Semiconductor. It serves as a dedicated supervisory circuit for monitoring single-input voltage levels. The device is distinct from variants featuring adjustable delays or different output types such as CMOS or open-drain configurations.

Replacement Considerations

BD5241G-1 is listed as a recommended replacement with similar package dimensions and detection voltage.
