XC6127N21D7R-G

Supervisors Overview

The XC6127N21D7R-G is a fixed-threshold voltage detector manufactured by Torex Semiconductor. It features a detection voltage of 2.1V and utilizes an open-drain output configuration. The device operates within a supply voltage range of 0.7V to 5.5V and supports a manual reset function. It is housed in a compact 4-USPN (0.90x1.2mm) package, suitable for surface-mount applications with an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Ultra-small USPN-4 package design for space-constrained PCB layouts
• High precision fixed threshold voltage detection capability
• Manual reset function allows external control over the reset state

Supervisors Applications

• Portable electronic devices requiring low standby current
• Battery-powered equipment needing reliable power supervision
• Embedded systems utilizing CMOS logic interfaces

Supervisors Procurement Notes

Verify the specific suffix D7R indicates the reel packaging format and tape width upon ordering. Confirm the 2.1V threshold matches the target circuit requirements. Ensure compatibility with the 4-USPN footprint during PCB layout finalization. Cross-reference the manufacturer's latest datasheet for any updates on compliance or pinout definitions before procurement.

Supervisors Selection Notes

Select this component when a precise 2.1V monitoring level is required for system stability. The open-drain output necessitates an external pull-up resistor for proper logic interface operation. Consider the manual reset feature if system recovery requires user intervention rather than automatic cycling. Evaluate the USPN-4 package dimensions against available board real estate constraints.

Supervisors Part Context

This part belongs to the XC6127 series of ultra-small voltage detectors from Torex Semiconductor. The series is characterized by high accuracy and low current consumption. Variants within the series differ primarily by their fixed detection voltage thresholds and output configurations, while maintaining consistent package and operational characteristics.

Supervisors Replacement Considerations

Direct replacements must match the 2.1V threshold, open-drain output, and USPN-4 package. Verify that alternative components support the same manual reset functionality and operate within the identical voltage and temperature ranges to ensure circuit compatibility.
