BD5328FVE-TR

Overview

The BD5328FVE-TR is a voltage detector IC from ROHM Semiconductor, designed for monitoring single-channel input voltages. It features a CMOS output type and operates within a supply voltage range up to 10 V. The device has a typical threshold voltage of 2.8 V with an accuracy of ±1%. It includes a programmable reset delay timer and lacks manual reset or watchdog functions. The component is housed in a VSOF-5 package, suitable for surface mount installation, and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• CMOS output interface for digital logic compatibility
• Programmable reset delay timer functionality
• High precision voltage detection with ±1% accuracy
• Wide operating temperature range for industrial applications

Applications

• Portable equipment power management
• Battery-powered system supervision
• General-purpose voltage monitoring circuits

Procurement Notes

Verify the obsolete status of this component before integration into new designs. Confirm availability through authorized distributors as stock may be limited. Ensure the VSOF-5 package footprint matches your PCB layout requirements. Check RoHS compliance documentation for regulatory adherence. Validate that the 2.8V threshold aligns with your system's voltage detection needs.

Selection Notes

Select this part when a fixed 2.8V threshold is required for single-input monitoring. The CMOS output is suitable for direct interfacing with microcontrollers. Consider the programmable delay if startup sequencing is necessary. Compare against the BD5228G-1 series for alternative pinout options if needed. Ensure the 10V maximum supply voltage covers your system's peak operating conditions.

Part Context

This component belongs to the BD53xx series of voltage detectors, which are characterized by low current consumption and adjustable delay times. It shares functional similarities with other parts in the BD52(53)xxFVE family but offers specific threshold and packaging configurations. The VSOF-5 package provides a compact solution for space-constrained designs requiring reliable voltage supervision.

Replacement Considerations

The BD5228G-1 is listed as a similar level replacement with the same pinout. Verify package compatibility between VSOF-5 and SSOP-5 if substituting. Check threshold voltage precision differences between the CMOS and open-drain output variants.
