BD5339FVE-TR

Overview

The BD5339FVE-TR is a CMOS voltage detector manufactured by ROHM Semiconductor, designed for supervisory circuit applications. It features a threshold detection voltage of 3.9 V with an accuracy of ±1%. The device operates within a supply voltage range of 0.95 V to 10 V and supports a programmable reset delay timer. It provides a low-active output in a VSOF-5 surface-mount package. The component functions without manual reset or watchdog capabilities and includes hysteresis defined as VDET x 0.05.

Feature Summary

• CMOS output architecture for low power consumption
• Adjustable reset delay timer functionality
• Integrated hysteresis for noise immunity

Applications

• Portable electronic devices requiring voltage supervision
• Battery-powered systems monitoring battery levels
• General-purpose microprocessor reset circuits

Procurement Notes

Verify the current lifecycle status before procurement, as this component may be classified as last-time buy or obsolete. Confirm RoHS compliance details through official datasheets. Ensure the VSOF-5 package dimensions match your PCB footprint requirements. Check for authorized distribution channels due to potential availability constraints.

Selection Notes

Select this part when a 3.9 V detection threshold is required with adjustable timing delays. Compare against similar models like BD5239G-1 if pinout compatibility or different output types are needed. Consider the operating temperature range of -40°C to +105°C for environmental suitability. Verify that the CMOS output type aligns with the downstream logic interface requirements.

Part Context

This component belongs to the BD52(53)xxFVE series of voltage detectors from ROHM Semiconductor. These parts are designed for compact surface-mount applications. The series offers various threshold voltages and output configurations. The BD5339FVE-TR specifically targets applications needing precise voltage monitoring with flexible reset timing control.

Replacement Considerations

BD5239G-1 is listed as a recommended replacement with the same pinout. Note that the substitute uses an SSOP-5 package instead of VSOF-5 and features an open-drain output rather than CMOS. Verify mechanical fit and electrical compatibility before substitution.
