BD5255FVE-TR

Overview

The BD5255FVE-TR is a voltage detector IC with an adjustable delay time, manufactured by ROHM Semiconductor. It features a typical under-voltage detection voltage of 5.5V with ±1% precision. The reset active voltage range spans from 0.95V to 10V, utilizing an open-drain output type. The circuit current is 0.85μA at VDET=4.8V. It operates within a temperature range of -40°C to 105°C and is housed in a VSOF5 package measuring 1.6x1.6mm with a thickness of 0.6mm.

Feature Summary

• Adjustable delay timer controlled by external capacitor
• High accuracy voltage detection with low current consumption
• Open-drain N-channel output for flexible interfacing

Applications

• Processor supervisor circuits
• Power supply monitoring systems
• Embedded system reset generation

Procurement Notes

Verify the specific ordering suffix TR for tape-and-reel packaging when sourcing. Confirm RoHS compliance status as indicated in official documentation. Check supply status carefully as this component may be subject to last-time-buy notices or obsolescence. Ensure the VSOF5 package dimensions match your PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when a precise 5.5V threshold is required with customizable reset timing. The adjustable delay feature allows designers to filter out transient noise effectively. Consider the open-drain output compatibility with various logic levels. Evaluate the low standby current for battery-operated applications requiring extended operational life.

Part Context

This part belongs to the BD52xx series of voltage detectors known for high accuracy and low power consumption. The FVE suffix denotes the VSOF5 package variant. It serves as a specialized supervisory circuit within ROHM's PMIC portfolio, designed for reliable system reset management in compact electronic devices.

Replacement Considerations

BD5250G-1 is listed as a recommended replacement with the same pinout but different package (SSOP5) and slightly different electrical characteristics such as a 5.0V detection voltage.
