BD5324FVE-TR

Overview

The BD5324FVE-TR is a voltage detector from ROHM Semiconductor, designed for monitoring single-input supply voltages. It features a typical threshold voltage of 2.4 V with ±1% precision. The device operates within a reset active voltage range of 0.95 V to 10 V and utilizes a CMOS output type. It includes an adjustable delay timer for reset timing control. The component supports a maximum power supply voltage of 10 V and functions reliably across a temperature range of -40°C to +105°C. It is housed in a VSOF-5 package.

Feature Summary

• Adjustable reset delay timer functionality
• CMOS output interface for digital logic compatibility
• High accuracy threshold detection with ±1% precision

Applications

• Portable electronic devices requiring precise power monitoring
• Embedded systems needing programmable reset delays
• Battery-powered equipment with low-voltage detection needs

Procurement Notes

Verify the obsolete status before procurement planning. Confirm availability through authorized distributors or last-time-buy channels. Ensure ECAD models are compatible with design tools. Check RoHS compliance documentation for regulatory requirements. Validate pinout compatibility if replacing existing components.

Selection Notes

Select this component when an adjustable delay timer is required alongside a fixed 2.4 V threshold. Compare against BD5224G-1 for similar specifications but different packaging. Consider the VSOF-5 footprint constraints during PCB layout. Verify that the CMOS output suits the downstream logic levels. Assess the operating temperature range against environmental conditions.

Part Context

This part belongs to the BD53xx series of voltage detectors, which offer programmable delay features. It is distinct from the BD52xx series by its adjustable timer capability. The BD5324FVE-TR is specifically engineered for compact surface-mount applications. It serves as a specialized solution for systems requiring precise timing control during power-up sequences.

Replacement Considerations
