BD4823FVE-TR

Overview

The BD4823FVE-TR is a standard CMOS voltage detector IC manufactured by Rohm Semiconductor. It features a detection threshold of 2.3V with ±1% precision. The device provides an open-drain output and operates within a reset active voltage range of 0.95V to 10V. It supports a supply voltage up to 10V, consumes 0.60μA in the ON state and 0.85μA in the OFF state at Vs=4.8V. Hysteresis is set at Vs x 0.05. The component is housed in a VSOF5 package (1.6x1.6mm) and functions across a temperature range of -40°C to 105°C.

Feature Summary

• CMOS technology for low power consumption
• Open-drain output configuration
• High accuracy voltage detection
• Compact surface-mount packaging

Applications

• Portable equipment power management

Procurement Notes

Verify current availability as the part may be obsolete or end-of-life. Confirm RoHS compliance and environmental certifications. Check for recommended replacements like BD5223G-1TR if sourcing new units. Ensure datasheet revisions match design requirements.

Selection Notes

Select this component for applications requiring precise under-voltage monitoring with minimal quiescent current. The open-drain output allows flexible interfacing with various logic levels. Consider the small VSOF5 package for space-constrained designs. Verify operating temperature ranges against environmental conditions.

Part Context

Part of the BD48 series voltage detectors from Rohm. Designed for simple reset/power-on-reset functions without manual reset or watchdog capabilities. Serves as a basic supervisory circuit for monitoring single voltage rails in consumer and industrial electronics.

Replacement Considerations

BD5223G-1TR is listed as a similar specification replacement with SSOP5 packaging.
