BD4845FVE-TR

Overview

The BD4845FVE-TR is a standard CMOS voltage detector IC from ROHM Semiconductor, designed for monitoring supply voltages in electronic systems. It features an N-channel open drain output and operates within a detection voltage range of 2.3V to 6.0V with 0.1V increments. The device offers high accuracy of ±1.0% and ultra-low current consumption of 0.8μA (typical). Packaged in the compact VSOF-5 format, it supports surface mount installation and functions across a temperature range of -40°C to +105°C, making it suitable for microcontroller and logic circuit supervision.

Feature Summary

• Provides precise voltage monitoring with ±1.0% detection accuracy
• Features ultra-low current consumption for energy efficiency
• Utilizes N-channel open drain output configuration
• Available in compact VSOF-5 surface mount package

Applications

• Microcontroller system power supervision
• Logic circuit voltage monitoring
• Battery-powered device reset control

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure storage conditions adhere to moisture sensitivity level guidelines to maintain device integrity during assembly processes.

Selection Notes

Select this component when a fixed threshold voltage near 4.5V is required with open-drain output compatibility. Consider the VSOF-5 package constraints for PCB layout space. Evaluate if the ±1.0% accuracy meets system tolerance requirements compared to higher precision alternatives in the BD49 series.

Part Context

This part belongs to the BD48□□G/FVE series of standard CMOS voltage detectors. It complements the BD49 series which offers CMOS push-pull outputs. Both series share similar low-power characteristics and accuracy levels but differ in output stage design, allowing designers to choose based on interface requirements with downstream logic components.

Replacement Considerations

BD4845G-TR: Similar specification with SSOP-5 package instead of VSOF-5.
