BD4836FVE-TR

Overview

The BD4836FVE-TR is a standard voltage detector manufactured by ROHM Semiconductor, designed for monitoring supply voltages in electronic circuits. It features an open-drain output type and operates within a reset active voltage range of 0.7 to 7 V. The typical under-voltage detection voltage is 3.6 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 utilizes a VSOF5 package and supports RoHS compliance.

Feature Summary

• Provides precise under-voltage detection with high accuracy for system supervision
• Features low power consumption suitable for battery-operated applications
• Includes hysteresis voltage functionality to prevent output oscillation

Applications

• Portable equipment requiring voltage supervision
• Battery-powered devices needing low standby current
• General-purpose circuit monitoring systems

Procurement Notes

Verify the obsolete status before procurement planning as this component may no longer be available for new orders. Confirm that the VSOF5 package dimensions match your PCB layout requirements. Ensure compatibility with the 3.6 V detection threshold for your specific application needs. Check for any lead-free or RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a fixed 3.6 V detection threshold is required with minimal external components. Consider the VSOF5 package size constraints during PCB design. Evaluate the low current consumption benefits against the need for open-drain output interfacing. Verify that the operating temperature range meets your environmental specifications.

Part Context

This part belongs to the BU4836 series of standard voltage detectors from ROHM Semiconductor. It serves as a compact solution for monitoring single-supply voltages in consumer electronics. The device is part of a broader family of supervisory circuits designed for reliability and efficiency in portable applications.

Replacement Considerations

BD5236G-1 is listed as a recommended replacement with similar specifications. Verify package differences between VSOF5 and SSOP5 layouts. Confirm electrical parameter alignment for seamless integration into existing designs.
