BU4824FVE-TR

Supervisors Overview

The BU4824FVE-TR is a CMOS voltage detector IC from ROHM Semiconductor, designed for monitoring single power supply rails. It features an open-drain output and operates within a reset active voltage range of 0.7 V to 7 V. The typical under-voltage detection threshold is 2.4 V with a precision of ±1%. The device consumes 0.40 μA in the ON state and 0.55 μA in the OFF state at VDET=4.8V. It supports a maximum supply voltage of 7 V, operates between -40°C and 125°C, and utilizes a VSOF-5 package.

Supervisors Feature Summary

• CMOS technology ensures low current consumption for battery-powered applications.
• Open-drain output allows flexible interfacing with various logic families.
• Adjustable delay timer enables customizable reset timing based on external components.

Supervisors Applications

• Microprocessor system supervision
• Portable electronic devices requiring low standby current
• Battery-operated equipment monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices, as this part may be subject to last-time-buy restrictions. Ensure packaging specifications match design requirements before procurement.

Supervisors Selection Notes

Select this component when a fixed 2.4 V threshold is required without manual reset functionality. Compare against BD5224G-1 if adjustable delay or different package constraints are needed. Verify that the open-drain output suits the target circuit's pull-up configuration.

Supervisors Part Context

Part of the BU48xx series of standard CMOS reset ICs. This series offers high accuracy and low current consumption with detection voltages ranging from 0.9 V to 4.8 V in 0.1 V increments. The BU4824FVE-TR specifically targets applications needing a 2.4 V detection point.

Supervisors Replacement Considerations

BD5224G-1 is listed as a recommended replacement with similar specifications but includes an adjustable delay timer and uses an SSOP-5 package instead of VSOF-5.

Supervisors FAQ

Does the BU4824FVE-TR include a manual reset function?

No, this specific model does not support manual reset operations.

What is the hysteresis voltage characteristic?

The hysteresis voltage is defined as VDET multiplied by 0.05.
