BD5226FVE-TR

Overview

The BD5226FVE-TR is a voltage detector with an adjustable delay time, manufactured by Rohm Semiconductor. It features an open-drain output and a low-active reset state. The typical under-voltage detection voltage is 2.6V with a precision of ±1%. The reset active voltage range spans from 0.95V to 10V. 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.

Feature Summary

• Adjustable reset delay timer functionality
• Open-drain output type for flexible interfacing
• Low circuit current consumption for power efficiency

Applications

• Microprocessor system reset circuits

Procurement Notes

Verify the supply status as this component may be subject to end-of-life restrictions or last-time-buy notices. Confirm RoHS compliance and packaging details such as taping specifications before procurement. Ensure the ordering part number matches the required variant to avoid compatibility issues with existing designs.

Selection Notes

Select this component when an adjustable delay timer is required for system reset sequencing. Consider the 2.6V threshold and wide reset active voltage range for compatibility with various supply rails. Evaluate the VSOF5 package size against board space constraints and verify thermal performance within the specified operating temperature range.

Part Context

This part belongs to the BD52xx series of voltage detectors from Rohm Semiconductor. It is designed for monitoring supply voltages in electronic systems. The FVE suffix indicates specific package and tape/reel configuration. Similar parts in the series offer fixed delays or different thresholds.

Replacement Considerations
