BD5225FVE-TR

Overview

The BD5225FVE-TR is a CMOS voltage detector IC from ROHM Semiconductor, designed for monitoring supply voltages in electronic circuits. It features an adjustable delay timer controlled by an external capacitor, allowing customization of reset timing. The device operates within a wide supply voltage range of 0.95V to 10V and provides a 2.5V typical under-voltage detection threshold with ±1% precision. It utilizes an open-drain output configuration and consumes low circuit current, typically 0.85μA at VDET=4.8V. The component is housed in a compact VSOF5 package (1.6x1.6mm) and supports an operating temperature range from -40°C to 105°C.

Feature Summary

• Adjustable reset delay time via external capacitor connection
• High accuracy voltage detection with ±1% precision
• Low power consumption suitable for battery-operated systems
• Compact VSOF5 surface-mount package design

Applications

• Processor supervisor circuits requiring precise voltage monitoring
• Battery-powered devices needing low quiescent current management
• Industrial control systems operating in extended temperature ranges
• Automotive electronics requiring robust voltage supervision

Procurement Notes

Verify the specific ordering suffix and package variant when sourcing, as the BD5225 series includes multiple pinout options such as SSOP5 and VSOF5. Confirm that the selected part matches the required detection voltage and delay characteristics for your application. Check current supply status, as some variants may be marked as last-time buy or obsolete. Ensure compatibility with your PCB footprint and reflow soldering profile specifications.

Selection Notes

Select this component when a small form factor is critical due to its 1.6x1.6mm VSOF5 package. Choose it over standard SSOP versions if board space is limited. Consider the adjustable delay feature if system startup sequences require customizable timing. Verify that the 10V maximum operating voltage meets your circuit's peak supply requirements. Ensure the open-drain output interface aligns with your microcontroller or logic input capabilities.

Part Context

The BD5225FVE-TR belongs to the BD52xx series of high-precision voltage detectors. This series is characterized by low current consumption and flexible timing control through external capacitors. The FVE designation indicates the VSOF5 package type, distinguishing it from other package variants like G-1 (SSOP5). The series supports detection voltages from 2.3V to 6.0V in 0.1V increments, providing versatile options for various power rail monitoring needs.

Replacement Considerations

BD5225G-1TR is a recommended replacement with similar specifications but uses an SSOP5 package instead of VSOF5. Both parts share the same 2.5V detection voltage and adjustable delay functionality. Verify pinout compatibility before substitution, as package dimensions differ significantly. The G-1 variant offers slightly lower current consumption but lacks the compact footprint of the FVE version.
