BD4941G-TR

Overview

The BD4941G-TR is a CMOS voltage detector IC from the BD49xxx series manufactured by ROHM Semiconductor. It provides a detection voltage of 4.1V with an accuracy of ±1%. The device features a CMOS output type and operates within a reset active voltage range of 0.95V to 10V. It does not include a manual reset pin, watchdog timer, or adjustable delay timer. The component is housed in an SSOP-5 package and is supplied in tape and reel packaging.

Feature Summary

• CMOS output interface for direct logic compatibility
• High precision voltage detection capability
• Low current consumption design

Applications

• Processor supervisor circuits
• Battery voltage monitoring systems
• Over-voltage protection mechanisms

Procurement Notes

Verify the specific suffix G-TR against the manufacturer's latest datasheet to confirm package dimensions and taping specifications. Ensure the 4.1V detection threshold aligns with system requirements. Confirm RoHS compliance status and lead times directly with authorized distributors as availability may vary.

Selection Notes

Select this component when a fixed 4.1V threshold is required without manual reset functionality. Compare against the BD5241G-1 for similar performance in an SSOP-5 package if alternative sourcing is needed. Consider the CMOS output drive capability relative to the load requirements of the downstream circuitry.

Part Context

This part belongs to the BD49xxx series of standard voltage detectors designed for general-purpose supervision. It complements other variants like the BD4930G-TR which offers different detection voltages within the same family. The series focuses on providing reliable power management supervision with minimal external component requirements.

Replacement Considerations

The BD5241G-1 is listed as a similar level replacement with comparable specifications and the same SSOP-5 package configuration.
