BD4924FVE-TR

Overview

The BD4924FVE-TR is a CMOS voltage detector manufactured by ROHM Semiconductor, designed for supervisory circuit applications. It features a threshold voltage of 2.4 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 µs. It consumes a typical operating current of 900 nA and dissipates 210 mW of power. The component is housed in a VSOF-5 package, supports surface mount installation, and functions reliably across a temperature range from -40°C to +105°C.

Feature Summary

• CMOS output type for low power consumption
• High precision voltage detection capability
• Compact surface-mount packaging design

Applications

• Portable electronic devices requiring voltage supervision
• Battery-powered systems monitoring
• General purpose microprocessor reset circuits

Procurement Notes

Verify the obsolete status before procurement as the component is marked as discontinued. Confirm availability through authorized distributors or last-time-buy channels if existing stock is required. Ensure the VSOF-5 package matches the target PCB footprint. Check RoHS compliance details against specific project requirements. Validate that the 2.4 V threshold aligns with system voltage levels.

Selection Notes

Select this component when a precise 2.4 V detection threshold is required for CMOS-based supervisory circuits. Consider the low quiescent current for battery-operated applications where power efficiency is critical. The VSOF-5 package offers a compact solution for space-constrained designs. Ensure the operating temperature range meets the environmental conditions of the intended application.

Part Context

This part belongs to the BD49 series of standard voltage detectors from ROHM Semiconductor. It is designed for simple reset/power-on-reset functions without manual reset or watchdog timer capabilities. The series typically targets cost-effective solutions for consumer electronics and industrial control systems requiring reliable voltage monitoring.

Replacement Considerations

BD4923FVE-TR: Similar package but different threshold voltage (2.3 V). BD4927FVE-TR: Similar package but different threshold voltage (2.7 V). BD49E34G-TR: Different package (SSOP-5) and higher threshold voltage (3.4 V). Verify electrical compatibility and pinout alignment before substitution.
