BU4244FVE-TR

Overview

The BU4244FVE-TR is a CMOS voltage detector manufactured by ROHM Semiconductor, designed for monitoring single-channel power supply voltages. It operates within a supply voltage range of 0.7 V to 7 V and features an adjustable reset delay timer. The device provides an open-drain output with a low-active reset state and maintains a detection accuracy of ±1%. It functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Adjustable reset delay timer functionality
• Open-drain output configuration
• Low quiescent current consumption

Applications

• Portable equipment power management
• Microprocessor system supervision
• Battery-powered device monitoring

Procurement Notes

This component is officially listed as End-of-Life (EOL) or Last Time Buy status by the manufacturer. Verify current availability through authorized distributors, as standard stock may be limited. Confirm RoHS compliance and package integrity upon receipt. Ensure design-in decisions account for potential obsolescence and long-term supply constraints.

Selection Notes

Select this part when a single-channel voltage monitor with adjustable timing is required. The VSOF-5 package suits space-constrained surface-mount designs. Consider the ±1% threshold precision and wide operating temperature range for industrial applications. Verify that the open-drain output interface matches the downstream logic requirements.

Part Context

The BU4244FVE-TR belongs to the BU42xx series of voltage detectors from ROHM. These devices are engineered for low-power applications requiring precise voltage supervision. The specific suffix indicates tape-and-reel packaging for automated assembly processes.

Replacement Considerations

BD5244G-1 is documented as a recommended replacement with the same pinout.
