BD4829FVE-TR

Overview

The BD4829FVE-TR is a single-channel voltage detector manufactured by Rohm Semiconductor, designed for supervisory circuit applications. It operates within a supply voltage range up to 10 V and features a fixed detection threshold of 2.9 V with ±1% accuracy. The device provides an open-drain output that asserts a low-active reset signal when the monitored voltage falls below the threshold. It is housed in a compact VSOF-5 surface-mount package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Provides precise under-voltage monitoring with a fixed 2.9 V detection threshold and high accuracy.
• Features an open-drain output interface compatible with various logic families for system reset generation.
• Operates reliably across a wide industrial temperature range without requiring external components.

Applications

• Microprocessor and microcontroller power supply supervision
• Battery-operated equipment low-voltage indication
• Portable electronic devices requiring efficient power management

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance and check for specific manufacturing date codes if required for legacy systems. Ensure proper handling procedures are followed during storage and assembly to maintain device integrity.

Selection Notes

Select this component for designs requiring a simple, low-cost voltage supervisor with a fixed 2.9 V threshold. Consider the open-drain output configuration for compatibility with pull-up resistors. Evaluate the VSOF-5 package dimensions against available PCB space constraints before finalizing the design.

Part Context

This part belongs to the BD48 series of standard voltage detectors from Rohm Semiconductor. It is specifically engineered for general-purpose power management tasks where reliable voltage monitoring is critical. The series offers various threshold options to suit different supply rail requirements.

Replacement Considerations

BD5229G-1TR is listed as a recommended replacement with similar specifications but differs in package type (SSOP5 vs VSOF5). Verify pinout compatibility and thermal characteristics before substitution.
