BD4827FVE-TR

Overview

The BD4827FVE-TR is a single-channel voltage detector IC from Rohm Semiconductor, designed for supervisory circuit applications. It features an N-channel open-drain output and operates within a supply voltage range of 0.95 V to 10 V. The device provides a typical detection threshold of 2.7 V with a precision of ±1%. It includes a reset delay timer of 100 µs and maintains accuracy across an operating temperature range of -40°C to +105°C. The component is housed in a VSOF-5 (SOT-665) surface-mount package.

Feature Summary

• Provides precise under-voltage detection with high accuracy tolerance
• Features an N-channel open-drain output for flexible logic interfacing
• Includes a built-in reset delay timer to ensure stable system recovery

Applications

• Processor supervisor circuits requiring reliable power monitoring
• Battery-operated devices needing low standby current consumption
• Embedded systems utilizing CMOS logic families

Procurement Notes

Verify the obsolete status and last-time-buy conditions before procurement. Confirm that the VSOF-5 package dimensions match the target PCB footprint. Ensure compatibility with the required 2.7 V threshold and open-drain output configuration. Check for RoHS compliance documentation if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a fixed 2.7 V threshold is required without manual reset functionality. The open-drain output necessitates an external pull-up resistor for proper operation. Consider the 100 µs reset delay for timing-sensitive applications. Verify that the supply voltage range covers the minimum and maximum operational requirements of the monitored rail.

Part Context

This part belongs to the BD48xxx series of standard voltage detectors. It is functionally similar to other members of the family but distinguished by its specific 2.7 V threshold and VSOF-5 packaging. The series is characterized by low current consumption and high detection accuracy suitable for general-purpose power management.
