BD4824FVE-TR

Overview

The BD4824FVE-TR is a single-channel voltage detector manufactured by Rohm Semiconductor, designed for supervisory circuit applications. It operates within a supply voltage range of 0.95 V to 10 V and features a typical under-voltage detection threshold of 2.4 V with ±1% precision. The device utilizes an open-drain output type and provides a low-active reset signal without manual reset or watchdog timer functionality. It is housed in a VSOF-5 surface-mount package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Monitors a single input voltage channel to detect under-voltage conditions relative to a fixed threshold.
• Provides a low-active reset signal via an open-drain output interface compatible with CMOS logic levels.
• Operates across a wide supply voltage range suitable for various digital system power rails.

Applications

• Microprocessor and microcontroller system supervision
• Portable equipment power management
• Battery-powered device voltage monitoring

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance and check for specific manufacturing date codes if required for legacy systems. Ensure the VSOF-5 package footprint matches the design layout. Review official datasheets for handling and storage precautions related to moisture sensitivity.

Selection Notes

Select this component when a fixed 2.4 V threshold is required for single-channel supervision. Consider the open-drain output capability for interfacing with various logic families. Evaluate the VSOF-5 package size constraints against available board space. Compare static current consumption and operating temperature range against system requirements.

Part Context

This part belongs to the BD48xx series of standard voltage detectors from Rohm Semiconductor. These devices are engineered for compact, low-power supervision tasks in consumer electronics and industrial control systems. The series offers various threshold voltages to accommodate different power rail specifications while maintaining high accuracy and low standby current consumption.

Replacement Considerations

BD5224G-1TR is listed as a similar specification replacement with an SSOP-5 package. Verify pinout compatibility and package dimension differences before substitution.
