BD5234FVE-TR

Overview

The BD5234FVE-TR is a voltage detector supervisory circuit manufactured by ROHM Semiconductor. It features a detection threshold of 3.4 V with an accuracy of ±1%. The device operates within a supply voltage range of 0.95 V to 10 V and supports an adjustable reset delay timer. It utilizes an open-drain output type and lacks manual reset, watchdog timer, or battery backup functions. The component is housed in a VSOF-5 package and complies with RoHS standards.

Feature Summary

• Provides precise voltage monitoring with a fixed 3.4 V detection threshold and high accuracy.
• Includes an adjustable reset delay timer for customizable timing control.
• Features an open-drain output interface compatible with various logic levels.
• Operates reliably across a wide industrial temperature range.

Applications

• Microprocessor system reset circuits
• Portable equipment power management
• Battery-operated device supervision

Procurement Notes

This component is officially classified as obsolete and no longer available for purchase from the manufacturer. Verification of current stock status through authorized distributors is required before integration into new designs. Engineers should confirm end-of-life notices and plan for component obsolescence management strategies accordingly.

Selection Notes

Select this part only if the specific 3.4 V threshold and adjustable delay characteristics match the design requirements. Note that the VSOF-5 package differs from standard pinouts; verify footprint compatibility. Consider the BD5234G-1 as a recommended replacement with similar functionality but a different SSOP5 package.

Part Context

The BD5234FVE-TR belongs to the BD52xx series of simple reset/voltage detector ICs. It is designed for low-power applications requiring reliable power supervision. The FVE suffix indicates the specific VSOF-5 surface-mount packaging configuration used in compact electronic assemblies.

Replacement Considerations

The BD5234G-1 is listed as a recommended replacement with the same pinout and 3.4 V threshold. However, it uses an SSOP5 package instead of VSOF-5, requiring PCB layout adjustments.
