BU4313FVE-TR

Overview

The BU4313FVE-TR is a CMOS voltage detector IC from ROHM Semiconductor, designed for monitoring single-channel power supply voltages. It features a detection threshold of 1.3 V with an accuracy of ±1%. The device operates within a supply voltage range up to 7 V and consumes a typical static current of 550 nA. It provides a CMOS output type and includes an adjustable reset delay timer. The component supports surface-mount installation in a VSOF-5 package and functions reliably across an industrial temperature range of -40°C to +125°C.

Feature Summary

• CMOS output interface for direct logic integration
• Adjustable reset delay timer functionality
• Ultra-low static current consumption for battery efficiency
• High detection accuracy with ±1% threshold precision

Applications

• Portable electronic devices requiring low standby current
• Microprocessor system power supply supervision
• Battery-operated equipment voltage monitoring
• Industrial control circuit reset generation

Procurement Notes

Verify the specific suffix TR indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation. Check current lifecycle status as sources indicate potential end-of-life or last-time-buy conditions. Ensure the VSOF-5 package dimensions match your PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when a fixed 1.3 V threshold is required with adjustable timing delays. Compare against BU4213FVE-TR if open-drain output is preferred instead of CMOS. Consider alternative thresholds from the BU49xx series if different voltage levels are needed. Verify that the 7 V maximum input voltage aligns with your system's supply rails.

Part Context

This part belongs to the BU43xx series of standard CMOS voltage detectors. It shares the VSOF-5 package form factor with other members like BU4344FVE-TR. The series offers various detection voltages in 0.1 V steps. It serves as a supervisory circuit for ensuring stable operation in embedded systems.

Replacement Considerations

BD5213G-1 is listed as a same-pinout replacement option. Note that BD5213G-1 uses an SSOP5 package instead of VSOF5. Verify pin compatibility and electrical parameter alignment before substitution.
