M51945BFP#CF0R

Supervisors Overview

The M51945BFP#CF0R is a single-function voltage supervisor IC from Renesas, designed for system resetting applications. It features an adjustable voltage detection threshold range spanning from 1.3V to 17V, allowing flexibility in monitoring various supply rails. The device operates with a supply voltage up to 18V and provides an active low reset output via an open drain or open collector configuration. It supports an operating temperature range of -30°C to +85°C and is packaged in an 8-pin SOP.

Supervisors Feature Summary

• Adjustable voltage detection threshold for flexible system monitoring
• High supply voltage tolerance up to 18V
• Active low reset signal generation
• Open drain/open collector output interface

Supervisors Applications

• Microprocessor system reset circuits
• Battery-powered device supervision
• Industrial control system power monitoring
• Consumer electronics voltage regulation verification

Supervisors Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified partners. Confirm package type matches the 8-SOP specification. Check date codes and lot numbers against quality standards. Ensure storage conditions comply with moisture sensitivity level requirements. Validate that the specific suffix CF0R aligns with required reel or tape specifications for automated assembly processes.

Supervisors Selection Notes

Select this component when a wide adjustable threshold range between 1.3V and 17V is required. Consider the 18V maximum supply rating for high-voltage systems. The open drain output necessitates external pull-up resistors for proper logic level translation. Evaluate thermal performance within the -30°C to +85°C operational window for environmental compatibility.

Supervisors Part Context

This part belongs to Renesas' single-function reset IC family, which focuses on bipolar products capable of handling higher supply voltages. It serves as a dedicated voltage detector and system reset generator, distinct from multi-channel supervisors. The series emphasizes reliability in industrial and automotive environments where stable voltage monitoring is critical for system integrity.
