BD5353FVE-TR

Overview

The BD5353FVE-TR is a CMOS voltage detector IC from ROHM Semiconductor, designed for monitoring single-channel supply voltages. It features a typical threshold detection voltage of 5.3 V with ±1% accuracy. The device operates within a maximum supply voltage of 10 V and supports an adjustable reset delay time controlled by an external capacitor. It utilizes a VSOF-5 surface-mount package and functions across a temperature range of -40°C to +105°C.

Feature Summary

• CMOS output interface for direct logic integration
• Adjustable reset delay time via external capacitor
• High detection accuracy with low current consumption

Applications

• Processor supervisor circuits
• Battery voltage monitoring systems
• General-purpose power supply supervision

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance documentation matches specific manufacturing batches. Validate package integrity upon receipt as the VSOF-5 form factor requires careful handling during assembly processes.

Selection Notes

Select this component when a fixed 5.3 V threshold is required with programmable timing delays. Ensure the application environment stays within the specified -40°C to +105°C operational range. Verify that the external capacitor selection aligns with the desired reset delay duration for system stability.

Part Context

This part belongs to the BD53xx series of high-precision voltage detectors. It shares family characteristics such as CMOS outputs and capacitor-controlled delays with variants like BD5352 and BD5356, differing primarily in their specific detection voltage thresholds.

Replacement Considerations

BD5250G-1 is listed as a same-pinout replacement option, though it differs in package type (SSOP5 vs VSOF5) and detection voltage (5.0 V vs 5.3 V). Verify pin compatibility and electrical parameter alignment before substitution.
