BD5245FVE-TR

Overview

The BD5245FVE-TR is a voltage detector manufactured by ROHM Semiconductor, designed for monitoring single-input power supply lines. It features an open-drain output and operates within a supply voltage range of 0.95 V to 10 V. The device provides a precise threshold detection voltage of 4.5 V with an accuracy of ±1%. It includes a programmable reset delay timer and lacks manual reset or watchdog functionalities. The component is housed in a VSOF-5 surface-mount package and supports industrial operating temperatures from -40°C to +105°C.

Feature Summary

• Offers high-precision voltage detection with ±1% accuracy for reliable system supervision.
• Features a programmable reset delay timer to accommodate various startup requirements.
• Utilizes an open-drain output configuration for flexible logic interfacing.

Applications

• Monitoring power supply voltages in embedded systems
• Supervising battery-powered devices requiring precise threshold detection
• Ensuring stable operation in industrial control circuits

Procurement Notes

Verify the current lifecycle status as the component may be listed as End-of-Life or Last Time Buy. Confirm RoHS compliance details through official datasheets. Check for availability of replacement parts such as the BD5245G-1 if this specific variant is discontinued. Ensure the VSOF-5 package dimensions match your PCB layout constraints before ordering.

Selection Notes

Select this component when a 4.5 V threshold is required with high precision. Consider the open-drain output for compatibility with various logic levels. Evaluate the programmable delay feature against fixed-delay alternatives. Verify that the VSOF-5 package fits the available board space. Check if the absence of a watchdog timer meets the application's safety requirements.

Part Context

This part belongs to the BD52(53)xxFVE series of voltage detectors from ROHM. These components are designed for compact applications requiring precise voltage supervision. The series offers various threshold options and packaging configurations to suit different design needs.

Replacement Considerations

The BD5245G-1 is identified as a recommended replacement with the same pinout. Note that it uses an SSOP5 package instead of VSOF5, requiring layout adjustments.
