BD5256FVE-TR

Overview

The BD5256FVE-TR is a CMOS voltage detector manufactured by ROHM Semiconductor, designed for supervisory circuit applications. It operates within a supply voltage range of 0.95 V to 10 V and features a typical under-voltage detection threshold of 5.6 V with ±1% precision. The device utilizes an open-drain output type and includes an adjustable reset delay timer controlled via an external resistor. It is housed in a compact VSOF-5 surface-mount package and supports operation across a temperature range of -40°C to +105°C.

Feature Summary

• Features an adjustable reset delay timer that allows customization of the reset pulse width using an external resistor connected to the DEL pin.
• Provides high-precision voltage monitoring with a typical detection accuracy of ±1% for reliable system supervision.
• Utilizes an open-drain output configuration compatible with various logic families for flexible interface integration.

Applications

• Microprocessor and microcontroller power supply supervision
• Battery-operated equipment voltage monitoring
• Industrial control system reset circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance and specific lot traceability requirements before procurement. Ensure ordering suffix matches the reel packaging specification. Validate technical specifications against the latest official datasheet to account for potential design revisions or obsolescence notices.

Selection Notes

Select this component when a fixed 5.6 V detection threshold is required alongside customizable reset timing. Compare against the BD5356FVE-TR if a CMOS push-pull output is preferred over the open-drain configuration. Consider the BD5250G-1 as a pin-compatible alternative if a 5.0 V threshold aligns better with the target application voltage levels.

Part Context

This part belongs to the BD52xxFVE series of voltage detectors from ROHM Semiconductor. These devices are engineered for low-power consumption and compact footprint requirements in portable and industrial electronics. The series emphasizes precise voltage monitoring capabilities integrated into small-scale surface-mount packages suitable for automated assembly processes.

Replacement Considerations

BD5356FVE-TR offers identical detection voltage but features a CMOS output instead of open-drain. BD5250G-1 provides a similar function with a 5.0 V threshold and SSOP-5 package, requiring layout adaptation.
