BD5244FVE-TR

Overview

The BD5244FVE-TR is a CMOS voltage detector with an adjustable delay time, manufactured by ROHM Semiconductor. It features a typical under-voltage detection voltage of 4.4V with ±1% precision. The reset active voltage range spans from 0.95V to 10V, utilizing an open-drain output type. The device operates within a temperature range of -40°C to +105°C and consumes a circuit current of 0.85μA when active (at Vdet=4.8V). It lacks manual reset and watchdog timer functions. The component is supplied in a VSOF5 package with taping packing.

Feature Summary

• Adjustable reset delay timer functionality
• Open-drain output configuration
• Low power consumption design

Applications

• General electronic equipment monitoring
• Portable devices requiring low standby current
• Battery-powered systems

Procurement Notes

Verify the supply status as Last Time Buy or End-of-Life before finalizing procurement plans. Confirm that the VSOF5 package and taping quantity align with manufacturing requirements. Ensure compatibility with existing PCB footprints and design specifications for the BD5244FVE series.

Selection Notes

Select this component when an adjustable delay timer is required alongside precise under-voltage detection. Compare against similar levels like BD5244G-1 if SSOP5 packaging or different electrical characteristics are acceptable. Verify that the open-drain output suits the downstream logic interface without additional pull-up components.

Part Context

This part belongs to the BD52xxFVE series of CMOS voltage detectors. It is designed for applications needing reliable supervision with customizable reset timing. The series offers various detection voltages and packages to suit diverse system architectures.

Replacement Considerations

BD5244G-1 is listed as a similar level replacement with the same pinout but differs in package (SSOP5) and electrical parameters such as hysteresis and operating temperature range.
