BD4744G-TR

Overview

The BD4744G-TR is a standard voltage detector manufactured by ROHM Semiconductor, designed for monitoring single-input power supply voltages. It features an open-collector output and operates within a supply voltage range of 0.85 V to 10 V. The device has a typical threshold detection voltage of 4.4 V with a precision of ±1%. It functions without manual reset or watchdog timer capabilities. The component supports surface-mount installation in an SSOP-5 package and operates across a temperature range of -40°C to +75°C.

Feature Summary

• Monitors single input voltage with high accuracy detection
• Provides open-collector reset output signal
• Operates without manual reset or watchdog timer functions

Applications

• Power supply supervision in electronic systems
• Microprocessor reset circuit generation
• Battery voltage monitoring applications

Procurement Notes

Verify current availability status as the component may be discontinued or subject to last-time buy restrictions. Confirm RoHS compliance details through official datasheets. Ensure compatibility with existing PCB footprint and electrical requirements before procurement. Check for recommended replacement parts if new designs are required.

Selection Notes

Select this component for applications requiring simple voltage monitoring with open-collector outputs. Consider the 4.4 V threshold and ±1% accuracy for precise reset timing. Evaluate the SSOP-5 package size for space-constrained designs. Verify operating temperature range suitability for the intended environment.

Part Context

Part of the BD47 series of standard voltage detectors from ROHM Semiconductor. Designed for general-purpose power management tasks where basic supervision is sufficient without complex timing or enable features.

Replacement Considerations

BD5244G-1TR is listed as a recommended replacement with similar package and detection voltage but offers adjustable delay and lower current consumption.
