Procurement Notes

Verify the BD5323FVE-TR is available for last-time-buy orders only. Confirm VSOF5 package compatibility with PCB footprint. Check RoHS compliance documentation. Ensure design freeze before procurement due to end-of-life status. Validate electrical parameters against system requirements.

Selection Notes

Select this component for applications requiring precise 2.3V detection with adjustable timing delays. Consider the VSOF5 package size constraints. Evaluate the CMOS output drive capability against load requirements. Verify operating temperature range suitability for the environment.

Part Context

Part of the BD53xx series of high-accuracy, low-current voltage detectors. Designed for portable devices and battery-powered systems. Offers programmable delay times via external components. Provides reliable supervision for microprocessors and memory devices.

Replacement Considerations

BD5223G-1 offers same pinout but different package (SSOP5) and open-drain output. Verify functional equivalence if transitioning packages.
