BD4854FVE-TR

Overview

The BD4854FVE-TR is a standard CMOS voltage detector IC from the BD48 series by ROHM Semiconductor. It features a threshold voltage of 5.4 V with an accuracy of 1%. The device operates within a supply voltage range up to 10 V and includes a reset delay time of 100 us. It utilizes an open-drain output type without manual reset or watchdog timer functions. The component is housed in a VSOF-5 package, suitable for surface mount technology (SMD/SMT).

Feature Summary

• High accuracy voltage detection with 1% tolerance.
• Low current consumption design optimized for battery backup applications.
• Open-drain output configuration for flexible interfacing.

Applications

• Portable electronic devices requiring precise power monitoring.
• Battery-operated systems needing low quiescent current supervision.
• General purpose voltage reset circuits in consumer electronics.

Procurement Notes

Verify end-of-life status before integration. Confirm availability through authorized distributors as stock may be limited. Ensure RoHS compliance documentation matches specific manufacturing dates. Validate package marking against official datasheet specifications to prevent counterfeit components during procurement processes.

Selection Notes

Select this component when a fixed 5.4 V threshold is required. Compare static current specifications against system power budgets. Verify VSOF-5 footprint compatibility with PCB layout constraints. Consider alternative BD48 series variants if different threshold voltages are needed for the application design.
