Overview
The BD5231FVE-TR is a voltage detector with adjustable delay time manufactured by ROHM Semiconductor. It features an open-drain output and operates within a supply voltage range of 0.95V to 10V. The typical under-voltage detection threshold is 3.1V with ±1% precision. Hysteresis is set at VDET x 0.05. Circuit current is 0.85μA at VDET=4.8V. Output currents are 0.4mA (Low) and 2mA (High). The delay circuit resistance is 9.0MΩ. Operating temperature ranges from -40°C to 105°C. Package is VSOF5, size 1.6x1.6mm.
Feature Summary
- Adjustable reset delay timer functionality
- Open-drain output configuration for flexible interfacing
- High detection accuracy with ±1% precision
Applications
- Microprocessor system supervision
- Battery-powered device monitoring
- Embedded system power management
Procurement Notes
Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status matches project requirements. Check datasheet revisions for parameter updates. Validate package marking against official specifications. Ensure storage conditions meet moisture sensitivity level guidelines before assembly.
Selection Notes
Consider the adjustable delay feature when timing constraints exist in reset sequences. Evaluate the open-drain output compatibility with target logic levels. Assess operating temperature range suitability for environmental conditions. Compare power consumption metrics against system battery life requirements. Verify package dimensions fit available PCB footprint constraints.
Part Context
This component belongs to ROHM's voltage detector family designed for supervisory applications. It provides reliable monitoring of supply voltages in electronic circuits. The adjustable delay allows customization for specific system startup requirements. Integration into compact designs is supported by the small VSOF5 package.
Replacement Considerations
BD5231G-1 is listed as a recommended replacement with same pinout. Note differences in package type (SSOP5 vs VSOF5) and operating temperature range. Verify electrical parameters match application needs before substitution.
