BD4846FVE-TR

Overview

The BD4846FVE-TR is a CMOS voltage detector IC manufactured by Rohm Semiconductor, designed for supervisory circuit applications. It features a threshold voltage of 4.6 V with a precision of ±1%. The device operates within a supply voltage range up to 7 V and utilizes an open-drain output type. It is housed in a VSOF-5 package and supports surface mount installation. The component has a reset delay timer of no adjustable delay and lacks manual reset or watchdog timer functions. It is rated for an operating temperature range from -40°C to +125°C.

Feature Summary

• CMOS technology ensures low power consumption and high accuracy voltage detection.
• Open-drain output configuration allows flexible interfacing with various logic levels.
• Compact VSOF-5 package facilitates space-constrained surface mount designs.

Applications

• Portable equipment requiring low voltage monitoring
• Battery-powered systems needing under-voltage detection
• General-purpose electronic circuits requiring power supervision

Procurement Notes

Verify the exact part number BD4846FVE-TR against official Rohm Semiconductor documentation to confirm specifications. Check current lifecycle status as components may be discontinued or subject to last-time buy notices. Ensure compatibility with your system's voltage requirements and package constraints before procurement.

Selection Notes

Select this component when a precise 4.6 V threshold is required for under-voltage detection. Consider the open-drain output and lack of internal reset delay when designing external timing circuits. Verify that the VSOF-5 package fits your PCB layout and that the operating temperature range meets your environmental conditions.
