BD4826FVE-TR

Overview

The BD4826FVE-TR is a standard voltage detector manufactured by Rohm Semiconductor, designed for surface-mount installation in VSOF-5 packages. It features an open-drain output with low-active reset signaling and monitors a single input channel. The device operates within a supply voltage range of 0.95V to 10V, detecting under-voltage conditions at a typical threshold of 2.6V with ±1% precision. It functions across a temperature range of -40°C to +105°C, consuming 0.60μA when active and 0.85μA when inactive at 4.8V supply.

Feature Summary

• Provides precise under-voltage detection with high accuracy for system monitoring
• Features low power consumption suitable for battery-operated applications
• Delivers open-drain reset output compatible with various logic families

Applications

• Portable electronic devices requiring efficient power management
• Battery-powered equipment needing reliable voltage supervision
• General-purpose industrial control systems

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS3 compliance and check for specific ordering suffixes if available. Validate package integrity upon receipt as the part is no longer in active production. Ensure compatibility with existing PCB layouts before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring a fixed 2.6V threshold with minimal quiescent current. Consider the VSOF-5 footprint constraints and open-drain interface requirements. Evaluate thermal performance within the specified operating range. Compare against newer alternatives like the BD5226G-1 if long-term availability is critical for the product lifecycle.

Part Context

This voltage detector belongs to the BD48 series, focusing on simple reset functionality without manual reset or watchdog timers. It serves as a cost-effective solution for basic power supervision tasks where advanced timing features are unnecessary. The series emphasizes compact packaging and low standby current for space-constrained designs.

Replacement Considerations

The BD5226G-1 is documented as a similar specification replacement. Verify pinout compatibility and electrical parameter alignment before substitution.
